what is the difference between a torque and a moment?

Answer 1

Altogether different things though measurement units and dimensions are same for both torque and moment. Please go through the below statement,

01 Applied load perpendicular to lenght of the object axis causes moment wherea as load applied on cross section of an object at a distance from its rotational axis causes torque
02 Moment always causes to alongation and compression of fibers of an object away from its neutral axis, where as torque always causes twisting of fibers.
03 moment defined as load multiplied by a distance of load from a fixed point where as torque is defined as multiplication of load and radius of rotation.

Answer 2

When dealing with rotating systems, a 'torque' the same as a 'force' in a straight line system. A 'moment' takes the place of 'inertia' (in fact, in most older texts it's calle 'moment of inertia' or 'inertial moment')

Answer 3

Maybe this will help you understand what the others are saying. Say you have a 1 horse power electric moter. In a moment of time it makes one turn and stalls. It has developed it's full horse power and torque in this one turn.

Answer 4

None

In physics, torque (or often called in physics a moment) can informally be thought of as "rotational force" or "angular force" which causes a change in rotational motion.
