In the above problem, what force should the man exert on the rope to get his correct weight on the machine?

Text Solution

Verified by Experts

`T-cancel(M)g+cancel(M)g=Ma`
`(because R=Mg)a=(T)/(M)`
`T-Mg-mg=ma`
`T-m(T)/(M)=(m+M)g`
`T=((m+M)Mg)/(M-m)=((30+60)60xx10)/(60-30)`
`= (""^(3)cancel(90)xx600)/(cancel(30))=1800N`
