Penjelasan Produk

Rubber blocks in shear force are often used on engine and in equipment mounting to isolate vibrations. They do this by absorbing shock energy by deforming. This deformation leads to a decrease in cross-section as the block lengthens, an effect described by Poisson's Ratio.
After this experiment, students will understand the behaviour of a very flexible material such as rubber. Rubber is interesting in that the lay person regards it as an 'elastic' material. In engineering terms it is not as 'elastic' as steel and often exhibits a high degree of hysteresis.
A rubber block 150 x 75 x 25mm is bonded to two vertical plates. The back plate secures the rubber block to a vertical surface such as a wall. The front plate allows a load hanger to be suspended and also the anvil of a dial gauge to rest.
The load hanger is loaded using the calibrated weights supplied and the corresponding vertical deflection of the rubber block is monitored using the dial gauge supplied.
A comprehensive instruction manual is supplied. No wall fixings are supplied.
