Pendulum Impact Testing Machine

The Pendulum is mounted on antifriction bearings. It has two starting positions, the upper one for Charpy & the lower one for izod testing. On release, the pendulum swings down to brake the specimen and the energy absorbed in doing so is measured as the difference between the height of drop before rupture and the height of rise after rupture of the test specimen and is read from the maximum pointer position on the dial scale.
