Question

If the maximum moment of force on a door is 10 Nm by an applied force of 2.25 N, then the

distance of handle from hinge (pivot) is

A. 0.225 m.

B. 4.444 m.

C. 12.250 m.

D. 22.500 m.​

Answer 1

Explanation:

moment of force = F x perpendicular distance from the axis of rotation.

10 = 2.25 x r

r = 10 / 2.25 = 1000/ 225 = 200/45 = 40/9 =4.444m
