Question

How is moment calculated in the following conditions:

i) When force is perpendicular with the distance between fulcrum and the line of action of force.

ii) When force is parallel to the distance between the fulcrum and the line of action of force.

iii) When force is forming an angle smaller than 90degree with the distance between the fulcrum and the line of action of the force.​

Answer 1

The moment of the force is equal to the product of the magnitude of the force and the perpendicular distance of the line of action of the force from the axis of rotation or fulcrum. ... If the force is not applied perpendicular on a lever, the value of moment decreases.
