moment with respect to the axis that goes through the point O
F
force
x
length of moment arm to the vertical component of F
theta
angle between F and the vector from point O to the position where quantity F is applied
Formula description
Moment of force (often just moment) is the tendency of a force to twist or rotate an object. A moment is valued mathematically as the product of the force and the moment arm. The moment arm is the perpendicular distance from the point of rotation, to the line of action of the force.
