pfft, yeah .. to me it looks like it should be balanced already assuming a uniform distibution of density.
other than that, i got nothing for this :/
very simple.
mje smjha do pls kaise kya krna hai smjh nhi aarha hai
Ixx= ?
|dw:1382806686885:dw| itna pata hai
yeh teek hai lekin rectangle ka batao.
rectangle ka ab alag se kbse hone lga?pta nhi mjhe..:(
|dw:1382806855821:dw|
mere book me solved hai pr kch smjh nhi aarha hai
b aur d kya hai?
yeh formula to aata hain na aapko ?
aur sbse pehle to centroid nikalna hai uske bd ye formula apply krnge naa
han han ab yad aaya
haan.
fir kya krna hai?step by step kripa krke mjhe smjhado mera test najdik hai
http://www.sut.ac.th/engineering/Civil/courses/410201/section_01/pdf/09_review.pdf proble 9.5 go through this !
kuch samaj me aaya kya ?
kch v smjh nhi aarha hai mjhe
ok.
solution to mere book me v hai pr mjeh smjhna hai
|dw:1382807188452:dw|
teek hain na ?
mere book me 3 areas me divide krdiya hai fir centroid nikalke inertia nikala hai
wait i will explain you step by step.
thanks...mtlb teeno ko alag krdiya naa
haan.
acha thik hai fir
|dw:1382807317715:dw|
|dw:1382807418785:dw|
ye formula me kaunsa chiz kya hai pls bta skte ho...ye wala mje smjh nhi aya tha
|dw:1382807451385:dw|
dy ^2 kya hai ar I x bar??
|dw:1382807499154:dw|
acha smjhi b aur d kya hai
Ix bar is your centroid.
aur dy^2?
|dw:1382807621966:dw|
|dw:1382807661192:dw|
|dw:1382807707926:dw|
acha
|dw:1382807753365:dw|
ok
we take dy wrt to xx axis===very important point to be noted.
ok i got it
fir???
|dw:1382808567090:dw|
|dw:1382808636733:dw|
teek.
ohh han..thk hai
|dw:1382808709885:dw|
han ok smjhi
|dw:1382808744770:dw|
|dw:1382808774994:dw|
ab ayega maza. listen carefully now.
lol...ok ok bolo
|dw:1382808843972:dw| dy for a =60+7.5
samaj main aaya kya ?
nahi
see i told u know to be careful. ok.
lekn hmlog 60+7.5 kyun lenge
smjh nhi aarha hai i hate mechanics
|dw:1382808989426:dw|
ohh distance from xx???
acha acha smjhi ab
for rectangle A WRT XX AXIS,YES. 60+15/2
OK U GOT THAT ONE RIGHT ?
yes got it
NOW CAN U DO THE SAME THING FOR RECTANGLE B ,I WILL HELP U OUT IF U ARE WRONG.
60??
OK FIRST DO FOR RECTANGLE C.
LEAVE THE CALCULATION FIRST TRY TO UNDERSTAND THE STEPS.
for rectangle c it will be same..60+15/2
DO SIMILAR STEPS AS I HAVE DONE FOR RECTANGLE C ALL THE STEPS PLZ,NOT ONLY dy.
follw the same steps.

very good.
thanksss :)

|dw:1382809467633:dw|
arre mtlb samw as A
|dw:1382809484431:dw|
SAME
let us go step by step.
area bta rhi hun
B ka dy kya hoga?
zero.
kyun?
that is only very important to know.
bcoz its centroid lies in xx plane isliye?
|dw:1382809613911:dw|
haan.
arre waah...bas itna hi steps hai naa hr type k sum find krne me?
is sum ka centroid v pls sikha do
now we shall find final answer.
nono..wo mai calulate krlngi first tell me centroid
aapko pehle hi bata dena tha naa,pehle centroid seekne ke baad hin moent of inertia jayenge?
did u follow all the steps ?
can u tell me Ix FOR A
yes...ohoo mai bhul gyi likhna centroid v sorry
OK
FIRST LET US COMPLETE THIS, OK ?
can u tell me Ix FOR A
