Answer 2

Given :  Nitesh applies an effort of 30 Newton on a simple machine through a distance of 1 metre and is able to push a load of 100 newton through a distance of 20 cm.

To Find :  the input output and efficiency of the machine.​

Solution:

Work done = Force * displacement

30 N Force

Distance = 1 m

Input Work done = 30 * 1 = 30 Nm

Load = 100 N

Distance = 20 cm = 20/100 m

Out put work done = 100 * 20/100  = 20 Nm

Efficiency  of the machine =  (20/30) * 100

= 66.67 %
