Question

A force of 50N is applied to a wheel.What is the moment of force? Explain with reason.​

Answer 1

Answer:

Force F=2 N

(1) :

Perpendicular distance between point O and B,   r=2diameter=22=1 m

Moment of force about centre O,   τO=rF=1×2=2 N m

(2) :

Perpendicular distance between point A and B,   r=diameter=2 m

Moment of force about centre A,   τA=rF=2×2=4 N m

Answer 2

Answer:

Answer:

Force F=2 N

(1) :

Perpendicular distance between point O and B,   r=2diameter=22=1 m

Moment of force about centre O,   τO=rF=1×2=2 N m

(2) :

Perpendicular distance between point A and B,   r=diameter=2 m

Moment of force about centre A,   τA=rF=2×2=4 N m
