Find the acceleration of movable pulled ...

Find the acceleration of movable pulled `P` and block `B` if acceleration of block `A =1m//s^(2)darr`.

Text Solution

Verified by Experts

The correct Answer is:
`a_(p) = 1m//s^(2) darr, a_(B) = 2m//s^(2) darr`
By virtual work method
`-T xx x_(A) +(T)/(2) xx x_(B) = 0 rArr x_(A) = (x_(B))/(2)`
`2a_(A) = a_(B) rArr a_(B) = 2m//s^(2)`
since pulled is directly attached to `A`,
so `|a_(P)| = |a_(A)| = 1 m//s^(2)`
