Descreiption of Oscillating Cylinder Apparatus

Oscillating Cylinder Apparatus comprises a sturdy base plate, which can be mounted vertically for demonstration purposes or flat for experimental use.

On the left of the base is a large rotating protractor scale 'Crank' that rotates on a shaft and bearing arrangement. The increments on the protractor match with a indicator that ensure accurate reading of the angular movement of the scale. Integral to this protractor are varying radius positions used for locating the crankshaft. Oscillating Cylinder Apparatus at the other end of the crankshaft is a slider that runs in a swivelling housing. A linear scale mounted to this housing ensures accurate readings of the piston displacement. An input disc can houses a crank pin, which can be fixed at various radii across the input disc face.

Oscillating Cylinder Apparatus a comprehensive instruction manual for lecturer and student, giving full details on apparatus assembly and operation as well as example results.

Experimental Capabilities of Oscillating Cylinder Apparatus

1. To determine the relationship between crank angle and stroke
2. To study the effect of changing the crank radius
3. To investigate by graphical differentiation the relationship between angular and linear speeds and accelerations of the mechanism
4. To construct velocity and acceleration diagrams for the mechanism
5. Comparison of experimental results with theoretical predictions
