two metallic cylinders made of the same material and radii r and 2r are joined as shown in the figure. if top end is fixed and lower end of cylinder B is twisted by angle Θ , then angle of twist for cylinder A is (both cylinder have the same length)WHY TWISTING TORQUE IS SAME IN BOTH THE METALLIC CYLINDER??
