Question

A Woman draws water from a well using a fixed pulley. The mass of bucket and water together is 6 kg. The force applied by the woman is 70 N. Calculate the mechanical advantage. (Take g = 10 m s^-2)

Answer 1

The force applied by the women = 70 N

The mass of bucket and water together is = 6 kg

Total load = 6 × 10 = 60 N

Mechanical advantage (M.A.) = `"𝐿𝑜𝑎𝑑"/"𝐸𝑓𝑓𝑜𝑟𝑡"= 60/70` = 0.857
