The Crank Mechanism "MBI", is a unit designed to observe, study and record the motion of a crank and the forces involved in a simple engine mechanism.
The piston is linearly displaced through a cylinder with the aid of a guide.
Bearings are coupled to the connecting rod so that friction is kept to a minimum.
There is a protractor attached to the crank, which can be rotated on the beam balance arm and locked in any predetermined angular position.
The piston displacement can be measured with a linear scale attached to the piston guide. The piston can be fitted with removable weights to change the piston mass.
The crank effort can be determined by attaching weights to the beam balance arm.
- Determination of the crank effort.
- Balancing of the crankshaft.
- Measurement of the piston displacement.
- Experimental relationship between piston displacement and crank angle.
- Theoretical relationship between piston displacement and crank angle.
- Comparison of the piston displacement value theoretically and experimentally.
- Experimental relationship between turning moment and crankshaft angle.
- Theoretical relationship between turning moment and crankshaft angle.
