A system of pulleys is used to lift a load of 1000 `kg_(wt)`. If the efficiency of the pulley system is 80% and velocity ratio is 20, find the effort required to lift the load.

Text Solution

Verified by Experts

To find M.A. use efficiency = `("Mechanical advantage")/("Velocity ratio")`
To find effort use, M.A = `("load")/("effort")`
