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
