Slipping Friction Apparatus

Slipping Friction Apparatus. This is a bench top apparatus for determination of sliding friction coefficient using an oscillating bar.

A round bar is placed on two counter turning pulleys driven by a variable speed motor with gear reducer. The distance between the two pulleys is adjustable. Measuring instruments for pulley speed and oscillation period are provided.

Instruction manual is also included.
