Q
moment of a force S.I. unit (3)
A
Nm or Neuton metre
for anti-clockwise, use +Nm
for clockwise, use -Nm
4
Q
moment formula
A
moment = force x perpendicular distance
5
Q
principle of moments definition
A
it states that if a body is not to rotate, the net clockwise moment must equal the net anti-clockwise moment
