A person using a 50cm long handled spanner can open a nut byapplying a 200 N forcee. What should be the length of the handle if hewants to open the nut by applying a force of 80 N

Answer»

Explanation:

moment of force = (200×0.5 ) Nm

= 100 Nm

if force is EQUAL to 80N

moment of force= 80N× X m

100 Nm=80x

x= 100/80

x = 5/4 m

if in cm = 5×100/4

= 125 cm
