Question

When an effort of 50 N is applied on a pair of pliers, it can overcome a load of 250 N. It is given that the distance between fulcrum and load is 6 cm. Find the length of the pliers. [36 cm]​

Answer 1

Ans: Effort : 50 N

Load: 250 N

Load arm: 6 cm

Effort arm: ?

       we know,

effort x effort arm: load x load arm

50 x EA (effort arm) : 250 x 6

EA :(250 x 6) / 50 : 30 cm

Thus length of pillars : EA plus LA ( load arm) : 36 cm
