Strain Rosettes Apparatus

The Equipment shall have the following facility:
Set-up consisting of hallow cylinder pasted with rosette strain gauge. This cylinder shall be pressurized by using foot pump. A multi channel strain indicator shall provided to measure out put of each strain gauge. Students can find out values of maximum stress at various pressures and compare the same with theoretical values.
