Stress and strain forces surrounding Torque can be investigated by means of this apparatus. A brass or steel rod may be fixed at either end and apply known forces to one end. The degree of rotation across the length of rod at different points can be measured by using three angle measures. Supplied with 2 no. of mounting rods, 3 levelling screws, 2 T-shaped assemblies, 2 no. of experimental rods (each of brass & steel), tripod base and 3 angle measurer attachments.
