Question

A spanner is 20 cm long.A force of 10 N is applied to undo a bolt.What is the moment(turning force)?

Answer 1

we know that

moment = Force * perpendicular distance from the line of action of force.

Given

F = 10N

R = 20cm

to convert centimetre into metre

20cm = 20/100m= 0.2 m

so

R = 0.2m

on putting on above formula

moment = 10*0.2 = 2Nm
