The following figure shows the combination of a movable pulley `P_(1)` with a fixed pulley `P_2` used for lifting up a load W.

State function of fixed pulley `P_2`.

Text Solution

Verified by Experts

Since the system has one movable pulley its mechanical advantage is 2.
As mechanical advantage = `("load")/("effort")`
effort =`("load")/("mechanical advantage")=(20)/(2)=10 kgf`
