clockwise is when the weight is on the right
anticlockwise is when the weight is on the left
2 factors have an influence on the rotation
magnitude of the force and distance between force and fulcrum
the lever arm is the distance between the point of application of the force and the axis of rotation(fulcrum)
formula torque : M=+-F. L
if the sum of the torque is equal to nil, then the object is in rotational equilibirum and the reverse is true :if the object is in rotational equilibrium, then the sum of torque is equal to zero
static equilibrium: no rotation
Dynamic equilibrium: objects rotates at constant rate in the same sens
M=torque (in n.m)
F=force ( in N)
L=lever arm (in m)
