determine the moment of inertia of a I-section.about xx axis.
koi to help krdo meri...m stuck in mechanics
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 :/
mje smjha do pls kaise kya krna hai smjh nhi aarha hai
|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
yeh formula to aata hain na aapko ?
aur sbse pehle to centroid nikalna hai uske bd ye formula apply krnge naa
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
solution to mere book me v hai pr mjeh smjhna hai
|dw:1382807188452:dw|
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

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.

|dw:1382807707926:dw|
|dw:1382807753365:dw|
we take dy wrt to xx axis===very important point to be noted.

ab ayega maza. listen carefully now.
|dw:1382808843972:dw| dy for a =60+7.5
samaj main aaya kya ?
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???
for rectangle A WRT XX AXIS,YES. 60+15/2
OK U GOT THAT ONE RIGHT ?
NOW CAN U DO THE SAME THING FOR RECTANGLE B ,I WILL HELP U OUT IF U ARE WRONG.
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.

|dw:1382809484431:dw|
let us go step by step.
that is only very important to know.
bcoz its centroid lies in xx plane isliye?
