Antara rasa-rasa dengan memang yakin

Peringatan untuk study dekat-dekat final pada masa hadapan


tolong ingatkan pada diri sendiri....jangan terlalu komfiden dengan diri boleh buat soalan tersebut semasa study jikalau dengan berpandukan jawapan.....

simpan jawapan.....semasa menjawap hanya perlukan soalan sahaja...

try sehingga betol2 dapat menjawap tanpa melihat jawapan.....(dan semak jawapan betol ke tidak)


kalau soalan tersebut dapat dijawap dengan betol tanpa melihat jawapan(cara kerja) barulah dikatakan betol2 dapat menjawap masa final.....

kalau tidak pasti masa final tak boleh jawab


rasa-rasa bukan membawa maksud boleh menjawab masa final, tetapi memang yakin dengan terbukti dapat menyelesaikan tanpa jawapan itulah sebenar-benar yakin

lu pikir la sendiri!!!!!!

Final oh final

entah macam mane perasaanku first day menghadapi final?? macam lah tak biasa...huuhu...entah bergegar tangan dan kaki sekali....pi dah lumrah seorg pelajar kan.....exam perlu untuk menguji tahap mana pencapaian seseorang....pi semua ni takde maksud apa-apa...just saje je.......to all my friend aku doa kan agar aku dan korang semua dapat jawab dengan sebaik yang mungkin semasa test english dan mathematic...sama-samalah kita saling berdoa antara satu sama lain....walaupun tak berapa pandai....berkat usaha kita insyallah, tuhan akan beri kejayaan kepada orang yang gigih berusaha......jangan mudah putus asa....(untuk ingatkan diriku jugak).....

NO.	Questions
1	Power Transmission       ·         Electrical power- transmission with underground cable(short-distance power)                                                              ·         Mechanical power- The oldest long-distance power transmission             - Transmission by gears             - Transmission by Belts             -Transmissions by ropes ·         Chemicals and fuels- radioactive isotopes, methane, hydrogen gas       4 gears (still tak berapa paham)       Only those who really u/s concept can answers
2	Types of belt   (http://www.roymech.co.uk/Useful_Tables/Drive/Flat_belts.html)       -flat belts       -Vee belts       -Timing belts       & arrangement of belt       Study necessary symbols “creep of belt” Creep theory describes the transmission of power between a running pulley and elastic belt. The name “creep” comes from the fact that frictional forces cause a change in belt tension thereby causing the elastic belt to extend and contract. This action results in relative motion between the belt and pulley surfaces which is termed elastic creep. The theory does make some simplifying assumptions concerning friction and elasticity which do not apply exactly to all materials. (still tak tau nak label) Fc = Centrifugal Force (N) R = Pulley reaction Force (N) P = Max power transferred kW T = Belt tension Tc = Belt tension due to centrifugal force μ = Coefficient of Friction. b = Belt width (m) ω = Angular velocity of pulley (rad/s) n = Rotational Speed (RPM) θ = Angle of belt lap v = Linear velocity of belt (m/s)       -Length of belt       (http://library.thinkquest.org/20991/geo/circles.html) 1. Problem: Find the length of a 24o arc of               a circle with a 5 cm radius.           Solution:      n             24           2(PI)               L = ---(2(PI)r) = ---(2(PI))5 = -----                   360           360             3                                                     The length of the arc is (2/3)(PI) cm.     -need to think/logic
3	Term primary balance, secondary balance, firing order         Primary balance is the balance achieved by compensating for the eccentricities of the masses in the rotating system, including the connecting rods. Primary balance is controlled by adding or removing mass to or from the crankshaft, typically at each end, at the required radius and angle, which varies both due to design and manufacturing tolerances. In theory, any conventional engine design can be balanced perfectly for primary balance. Secondary balance can include compensating (or being unable to compensate) for: The kinetic energy of the pistons. The non-sinusoidal motion of the pistons. The motion of the connecting rods. The sideways motion of balance shaft weights. The firing order is the sequence of power delivery of each cylinder in a multi-cylinder reciprocating engine. This is achieved by sparking of the spark plugs in a gasoline engine in the correct order, or by the sequence of fuel injection in a Diesel engine. When designing an engine, choosing an appropriate firing order is critical to minimizing vibration and achieving smooth running, for long engine fatigue life and user comfort, and heavily influences crankshaft design       4masses
4	Term flywheel, coefficient of energy, coefficient of speed A flywheel is a rotating disk used as a storage device for kinetic energy and smooths the operation of a reciprocating engine The ratio between the energy transmitted forward in a wave per unit crest length at a point in shallow water, and the energy transmitted forward in a wave per unit crest length in deep water. The coefficient of speed fluctuation Cs is defined as where ω = rotational speed at the flywheel and ωavg = average of ωmax and ωmin. Ranges for Cs for several categories of speed variation are given in the following table. Assume that the system is stiff (the speeds of all shafts are proportional)

Helicopter

Masa kecik2 dulukan memang nak jadi paramugara kan or pilot....yeke?..hahaha....rekaan semata-mata......
sbb hajat tak kesampaian disebabkan bidang sekarang lain dari yg sepatutnya...so kenelah ubah plan ......wlpn tak dpt control helicopter or kapal terbang  sebenar cukup la sekadar kontrol helicopter mainan...huhu......time krismas....datang seorang ermmmm...santa klous kan...gi umah anta hadiah....tgk2 die bagi hadiah...then i terkejut la jugak kan....bukak2 chek2 helicopter la.....fuhhhh..mmg baik la santa klous ni....(mengarut...ihihihi)......so skrg hajat tercapai wlpn serupa tapi tak sama kan.....helicopter tetap nama helicopter....time promotion harga 60 kalau nak diikotkan harga sbnr 199...pandai orang sekarang bisnes kan?....kalau dah RM199 buat je la RM200 buat ape nak kelirukan customer kan.....indah percakapan...pi harga mengelirukan......tapi apa nak buat kan...kalau nak sendiri kene buat la..uhuhu...
helicopter ni terbang tu memang la terbang...tapi time berada di awangan tu....badan2 ikot pusing sekali....memang kalau nak kontrol tu memang teramat la susah......sy rase kan orang pro mcm mana pon mmg susah nak kontrol helicopter ni....maybe sbb saiz tak brp besar sangat kot...then pasal beteri pulak...dalam 15minit macam tu la dah abis..kalau nak main gi kene la cas balik.....baru datang mode main bende ni kan pastu beteri abis...so jadilah kau benda perhiasan....kalau dah terlampau boring baru main kot....maklum la bujet tak cukup......beli besar2 pon nak main katne kan.....just for hilangkan boring cukup ar.....hari tu nak beli gitar sbnrnya.siap mesej no orang punya gitar dalam mudah.com....tapi tak jadi...huhuuh..tak jadi sbb tgk hadis2 dan laman web islamiah kan....macam bagitau gitar tu haram...wlpn de gak yang ckp harus.....pi takpe la terpulang pada individu...pi sy just mls nak beli.....

cinta sepi

mentari

gadisku

dialah gadisku selalu...........

titian usang

aku yang sedang meniti titian usang
berkemungkinan jatuh,,.............

stress..........

tension betol la blaja macam ni....asyik cancel kelas tiap2 hari.........
dah la minggu ke berapa dah ni......
bab2 yang diblaja belom start lagi....
malas la nak blaja kalau terus macam ni.............
tiap2 sem mesti macam ni kew?

termo...................

inilah termodynamics..........perubahan dari liquid ke vapor......camne tekanan.......dan keadaan fizikal....dalam keadaan cecair or gas....
boleh tahan gak la.....

camni rupanya ooo....first2 saturated liquid pastu compress liquid......then critical point saat nak bertukar jadi gas.....(mix)......then saturated vapor.....yang seterusnya superheated diluar tu....



The properties listed in the tables include

• Saturation pressure (P_sat) for a given temperature or saturation temperature (T_sat) for a given pressure
• Specific volume of saturated liquid (v_f) and saturated vapor (v_g)
• Specific internal energy of saturated liquid (u_f), saturated vapor (u_g), and vaporization (u_fg = u_g - u_f) jgn silap fg=g-f
• Specific enthalpy of saturated liquid (h_f), saturated vapor (h_g), and vaporization (h_fg = h_g - h_f) or latent heat of vaporization.
• Specific entropy of saturated liquid (s_f), saturated vapor (s_g), and vaporization (s_fg = s_g - s_f)

The above process can be repeated for u and h.
      u_av = u_f + u_fg x
      h_av = h_f + h_fg x        jgn silap  < rumus perlu dihafal

The format of the subcooled liquid water tables is similar to the format of the superheated vapor tables. In the absence of compressed liquid data, a common practice is to use the saturated liquid data based on the given temperature to estimate the properties of compressed liquid. For h, the error can be reduced using the following approximation
      
Subcooled liquid (compress liquid) can be characterized by

• P > P_sat at a given T
• T < T_sat at a given P           <hafal      superheated berlawanan compress
• v < v_f at a given P or T
• u < u_f at a given P or T
• h < h_f at a given P or T

untuk apa???

untuk apa semua ini......hanya sekadar membazir masa hidupku....

perlukah aku terus meneruskan cara hidupku yang begini.....

lebih baik mencari sesuatu yang lebih membawa kebahagiaan dan kerjayaku.....

kenangan bersamamu

Kasihku... usah dikau pergi

Kau tinggalkan diriku sendiri

Ke mana harusku cari ganti

Senyuman yang semanismu

Kini kau tiada lagi di sisiku

Ku kehilangan tempat bermanja

Kau pergi tanpa kerelaanku

Hatiku luka, hampa dan kecewa

Hanya kenangan terukir di dada

Bersemadi dalam sanubariku

Jiwa membara memendam rasa

Tersemai seribu pengertian hidupku

insan mencari cinta

 pe jiwang karat ni?????
pleazs la tolong la...tak main jiwang2 karat camni....



n tak terima org seadanya

sy pon tak tau camne nak kontrol diri

9:43am

:)

9:43am

kdg2 sy pon letih gak nak mlyn perangai sy sendiri

sukar nak tau camne

jodoh takde la tu

10:06am

:)

blum smpi msa la 2

10:06am

tula

kalau sy nak khwn pon 28

kalau awl2 kapel maybe sy takleh kontrol kot

blum jumpa org seswai 2

2 pasl jdi mcm 2

sy pun dlu cmtu gak

heheheh

10:12am

sy hairan dulu kan bukan nak kate play boy

pi de je kapel dgn ppuan

pi skrg hidup sy mcm ditakdir tak boleh kapel dulu

n sy dulu senang syg n terima org

pi sekrg lain

hairan

kalau dulu sy kalau takde psgn camni

sy kapel je dgn mane2 org yg sy nak

pi sy tak nak main kan prsn org

biar la sy merana keseorangan

sbb ni diri sy sy tak nak babit kan org lain

tak nak perlu disaat sunyi

mcm dulu terima je

janji sy bahgia

tak peduli pon persn org lain

bile de ppuan baik gi tukar

tu dulu

pi bile sy tak perangai mcm dulu

hidup sy sunyi

n psgn susah nak dtg

pelik kan

sory la sbb awk ppuan

10:18am

hehehhe

urmmm..

2 la

dlu nakal sgt!

10:18am

pi kalau kite penting kan diri kapel2 senang dtg

pi kalau kite menghargai diri org lain kite pulak yg merana atas diri kite

biar la

biar la sy sunyi

tak nak main prsn org lain

tak nak perlu disaat sunyi

sbb org lain pon ada hati prsn

pi sy sunyi

n mkn tak kenyang

tido tak lena

blaja takle fokus

semua ni terpaksa tempuhi

10:22am

cri la couple yg mbina

yg boleh buat dorongan

10:22am

tapi takut sy tinggalkan die wak

org yg syg kat kete boleh je bagi dorongan

pi bile kite dh capai sesuatu kite tinggalkan die

tak nak la camtu

sy nak die syg sy n sy syg die

tak nak bertepok sblh tgn

ti org sedih

10:25am

urmmm

cri la kwn rpt pmpn..

xbole?

10:25am

kalau kwn pon lain

susah nak share

n nak syg2 pon takle

rase org syg kat kite takde

huhu

sbb kwn je kan

feel kwn dgn gf lain

10:27am

bg sy la

pcintaan mrupakan psahabatan

that y ada yg couple dgn bestfnd in the end

huhu

10:28am

mmg la pi persahabatan tak semestinya percintaan

10:28am

so, sy lyn bf sy tu mcm kwn je

ktorg sempoi je

10:28am

n susah kite nak hantar you are my everything

hih

kalau dgn kwn susah nak kate mcm tu

melainkan die tu lebih dari kwn

n die tau

yg die syg kat awk

n awk syg kat die

sy de ppuan

die ckp nak kapel dgn sy

pi sy ckp sanggup ke dgn sy

boleh ke sy terima die

pi sy takut diri sy ni

senang tinggalkan org time hapy

10:31am

urmmm..

sbr la

jgn dok fkr sgt bab2 couple nie

nti dia akn dtg la 2 k

LOVE is not about finding the right PERSON, but creating a right RELATIONSHIP...Its not about how much LOVE u have in the BEGINNING, but how much LOVE u build till the END...‌

10:33am

but to create one relationship dificult for me

becouse if me not really love her

i will leave her

so what can i do

so difficult

if im waiting

all my live be boring

cant do anthyng focusly
