The
moment
of an object is the
turning effect
of a
force
on an object.
Moment of Force (Nm) =
Force
(
N
) x
Perpendicular Distance from
the
Pivot
(m)
Moment is measured in
Newton Metres
(
Nm
)
Torque is the
twisting
action caused by a
force
applied to an object
If an object is in balance it will not turn about a
pivot.
Sum of
anticlockwise
moments = Sum of
clockwise
moments
Force 1 Distance 1
=
Force 2 Distance 2
The
centre
of
gravity
is the point where the whole of the
weight
of the object appears to act
