Question

3) A force of 120 N is applied perpendicularly on a spanner at a distance of
9 cm from a nut. The moment of force produced will be​

Answer 1

Answer:

force = zero

Explanation:

because angle between them is 90°

and cos 90 equal zero

Answer 2

Given:

Force applied(F)=120N

Perpendicular distance(d)=9cm=9÷100m=0.09m

Moment of force produced=?

To find the the moment of force produced

Solution:

Moment is the turning effect of force. It is expressed as force multiplied by the perpendicular distance and given as,

$moment= f \times d$

Moment=120×0.09

Moment=10.8Nm

Thus, the moment of force produced is 10.8Nm.
