Web1. The torsional stiffness, or the torsion constant, κ, is defined as the amount of torque needed to rotate one end of a wire by 1 radian about the longitudinal axis of the wire with the other end being fixed. What do you think will happen to the torsion constant as you use a wire of the same material and length but with a larger diameter? 2. WebAnd let's say that that force is-- I don't know, let me make up something, that's 5 meters to the left of the pivot point. If I were tell you that this object does not rotate. So if I tell you that the object is not rotating, that means the net torque on this ruler must be 0, because it's not-- its rate of change of rotation is not changing.
