Question

A nut is opened by a wrench of length 20 cm. If the least force required is 2 N, find the moment of
fonce needed to loosen the nut.


Chalo chup chap solve karo xd ​

Answer 1

Answer:

we have

Moment of load about the fulcrum = Moment of effort about the fulcrum

Load x Load arm = Effort x Effort arm

Given that the effort arm 20 cm = 0.2 m, the minimum force E = 2 N

Therefore, the moment of load or the moment of force 0.2 x 2 = 0.4 Nm

The moment of force needed to looser

the nut = 0.4 Nm

Answer 2

Answer:

force=2N

distance=0.2m

moment of force =f×d=0.4 NM
