Crank Mechanism.
Crank Mechanism

The apparatus is intended to represent a simple engine mechanism and may be used by the students for simple experiments to investigate:

  • The relationship between the piston displacement and the crank angle for a given connecting rod/crank radius ratio.
  • The relationship between the turning moment on the crank shaft and the crank angle for a given force on the piston.

Technical specifications

  • The piston is fitted with brass rollers running on guide bars and needle roller bearings are fitted in the connecting rod so that friction is reduced to a minimum.
  • A protractor is attached to the crank which may be rotated on the beam balance arm and clamped in any predetermined angular position.
  • A linear scale is attached to the piston guide so that the piston displacement can be measured.
  • The crank effort may be determined by attaching suitable masses to the beam balance arm.
  • Experiment manual

Optional equipment :

  • The unit may be wall mounted or fitted to the Universal Bench Mounting Frame.
