Question

In figure, draw a tackle to lift the load by applying the force in the downward direction. What is the mechanical advantage of the system?

Answer 1

Given:
The block and tackle system consists of 5
pulleys,
L = 5T and E = T
Hence, Mechanical advantage
$M.A.=\frac{load\left(L\right)}{effort\left(E\right)}=\frac{5T}{T}=5.$
Thus, the mechanical advantage is equal to the
number of pulleys in both the blocks. i.e., 5.
