Text Solution

Verified by Experts

Find out the shift in point B, C and D
`DeltaL_(B)=DeltaL_(AB)=(FL)/(AY)=(MgL)/(AY)=(10xx10xx0.1)/(10^(-7)xx2.5xx10^(10))=4xx10^(-3)m=4mm`
`DeltaL_(C)=DeltaL_(B)+DeltaL_(BC)=4xx10^(-3)+(100xx0.2)/(10^(-7)xx4xx10^(10))=4xx10^(-3)+5xx10^(-3)=9mm`
`DeltaL_(D)=DeltaL_(C)+DeltaL_(CD)=9xx10^(-3)+(100xx0.15)/(10^(-7)xx1xx10^(10))=9xx10^(-3)+15xx10^(-3)=24mm`
