1F10.10inertia balance1F10.10A torsion pendulum has cups that can be loaded with various masses.
1F10.10inertia balanceMz-2A light torsion pendulum can be loaded with various masses.
1F10.10inertia balanceM-106Torsion pendulum as an inertia balance.
1F10.11inertia balance - leaf springPIRA 1000
1F10.11inertia balance8-2.7A horizontal leaf spring as an inertial balance.
1F10.11inertia balanceDisc 08-24Place masses on a platform supported by horizontal leaf springs.
1F10.12inertia oscillation8-2.5A puck between two springs rolling on Dylite beads is timed with several different masses.
1F10.13inertial equal arm balanceAJP 29(6),viPublication of an unfinished demonstration, but up front about it. Shows circuit diagram for a indicator for a horizontal Roberval type balance on an acceleration cart.
1F10.13inertia balanceTPT 11(5),312Measure the period of a commercially available (?) inertia balance by using a stroboscope.
1F10.20inertia bongsPIRA 1000
1F10.20inertia bongs1F10.20Hit hanging 2"x4"x10" blocks of wood and steel with a hammer.
1F10.20inertia bongsTPT 12(1),30Two large cylinders are suspended, one wood (3Kg) and one iron (50Kg). Students compare displacements when struck by a hammer or just push the things around.
