Torsion of Metal Rods Apparatus shows students the affect of a torque on a metal rod.

• Two Graduated Scales
• Heavy-Metal Pulleys
• Connected Rods
• Two Pointers
• For demonstrating the Affect of a Torque on a Metal Rod

Connected rods hold two heavy-metal brackets together. A heavy-metal pulley, moving in ball bearings, is mounted on one bracket and is fitted with a three-jaw chuck to hold one end of the test rod. The other end is held in another chuck fixed to the other bracket. Two graduated scales are mounted on the connecting rod, and two pointers can be clamped in any desired position on the test rod with one brass and one steel test rod.

Hanging masses and C clamps are required but sold separately. For best results, use masses heavier than 1 kg.
