Geetu draws water from a well using a fixed pulley. The mass of the bucket and water together is $6 kg$ . If the force applied by her is $70 N$ , calculate the mechanical advantage. (Take $g = 10 {m s}^{- 2}$ )
0.857

Open in App

Solution

The correct option is A 0.857
Given:
The effort = $70 N$
The mass of the bucket and water together, $m = 6 kg$

So, the total load = $m \times g = 6 \times 10 = 60 N$

Mechanical advantage, M.A. $= \frac{Load}{Effort} = \frac{60}{70} = 0.875$
