The HVT12B allows a number of torsional experiments to be applied to rod specimens. A vertical backboard is fixed to the HVT12F (not supplied), and assists the securing of the top end of the rod. Along the length of the rod can be attached a solid disc. Additionally a solid ring and split ring are included, that fit onto the disc to increase the overall inertia.
Different end conditions can be introduced by allowing the bottom end of the wire to be free or fixed..
The bottom end clamp allows length of the rod o be varied thus changing the frequency (Periodic Time). The protractor can measure deflection along the rod. A support frame, damping cylinder and tank enable controlled damping to be applied.
Includes steel and brass rods complete with clamps and adaptors.
