Question

A pulley can raise a load of 280 kg by applying an effort equal to 40kg weight.What is the mechanical advantage of the pulley?

Answer 1

Answer:

7

Step-by-step explanation:

load = 280kg

effort = 40 kg

mechanical advantage = load / effort

                                      = 280/40

                                      =  7

Answer 2

Answer:

no mechanical advantage

Step-by-step explanation:

A pulley doesn’t have any mechanical advantage when it is alone. But when there is a system of pulley, it has some mechanical advantage.

In the question there is only one pulley that can raise a load of 280 Kg by applying an effort equal to 40 Kg weight. So, there will be no any mechanical advantage in it.
