... The lever arm is the shortest distance from the line of force to the reference point. EXAMPLE: There are three forces acting on the mass-less rod and we calculate the moment arm (or lever arm) and torque for each force. 1. The 68.2 Nt force has a moment arm of about 2.1 m. The torque t1 associated w ...

... Objects acted on by gravity alone are in free fall. For an object of mass m, its weight = m g, where m is the mass of the object and g is the gravitational field strength at the object. The acceleration of the object, a, is the force of gravity divided by the mass = m g / m = g. Hence the accelerati ...
