## General Description

The Scotch Yoke Mechanism, "MYE", designed by EDIBON, is an example of slider-crank mechanism for converting the linear motion of a slider into rotational motion or vice versa.

It is made of aluminum and consists of a rotary element, called crank, with a graduated disc. This element and a piston are linked to a vertical pivot. The rotating motion of the crank generates the alternative linear motion of the piston.

It is a reversible system, if the piston generates the input motion (for example, a piston in a car's engine), the crank rotates.

The input angle is set on the ball bearing mounted crank disc and it is read on an angle measuring scale. A millimeter scale is fitted to measure the linear motion of the connecting rod.

## Exercises and guided practices

### GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL

1. Study of the conversion of smooth rotary motion into purely harmonic reciprocating motion.
2. Demonstrating the behaviour of a simple crank-driven Scotch yoke mechanism.
3. Plotting the relation between the linear displacement of the Scotch yoke and the angular displacement of the crank.
4. Determining the velocity and acceleration of the Scotch yoke by graphical differentiation.
5. Comparing the values obtained by the equations of motion.
