Question

2. The perpendicular distance between the point of application of force and the turning point is 1.75m, when a force
of 80 N acts on a rigid body. Calculate the moment of force.
[140 Nm]​

Answer 1

Answer:

Given :-

• The perpendicular distance between the point of application of force and the turning point is 1.75 m, when a force of 80 N acts on a rigid body.

To Find :-

• What is the moment of force.

Formula Used :-

$\clubsuit$ Moment of Force :

$\longmapsto \sf\boxed{\bold{\pink{Moment\: of\: Force =\: Force \times Perpendicular\: Distance}}}$

Solution :-

Given :

$\bigstar$ Perpendicular Distance = 1.75 m

$\bigstar$ Force = 80 N

According to the question by using the formula we get,

$\implies \sf Moment\: of\: Force =\: 80\: N \times 1.75\: m$

$\implies \sf Moment\: of\: Force =\: 80\: N \times \dfrac{175}{100}\: m$

$\implies \sf Moment\: of\: Force =\: \dfrac{140\cancel{00}}{1\cancel{00}}\: Nm$

$\implies \sf Moment\: of\: Force =\: \dfrac{140}{1}\: Nm\:$

$\implies \sf\bold{\red{Moment\: of\: Force =\: 140\: Nm}}$

$\therefore$ The moment of force is 140 Nm .
