Moment of force is defined as ..............
in term of F (force) and d (distance)
Moment = F/d
Moment = Fxd
Moment = F+d
Moment = F-/d
The SI unit for moment of force is
N/m
N/m2
Nm
Nm2
Two types of moment force are
Clockwise and Anti-clockwise
Stable and Unstable
Vertical and Horizontal
Forward and Backward
Moment is also known as
action of torque
action of moment
action of force
turning effect
The principle of moments states that when in equilibrium
sum of clockwise moments is more than with the sum of anti-clockwise moments
sum of clockwise moments is less than with the sum of anti-clockwise moments
sum of clockwise moments is equal with the sum of anti-clockwise moments
sum of horizontal force is equal with the sum of vertical force
Moment of force is 6 Nm and the distance of pivot is 2 m, force applied would be
