Torque, in the context of a body with a fixed axis of rotation, can be generated by any force that is not acting directly towards or away from the axis of rotation. This is because torque is the product of the force applied and the perpendicular distance from the axis of rotation to the line of action of the force. Forces acting directly towards or away from the axis do not create torque because their line of action passes through the axis, making the perpendicular distance zero.
