Features
Tesca Slider Crank Mechanism is a quick-return mechanism. This mechanism is  a combination of an inversion of the slider-crank chain and slider block. 

The unit is assembled in an anodized aluminum profile structure, with steel painted panel.  
The mechanism able to transform circular movement into reciprocating movement. It is made of  aluminum and consists of a rotary element (graduated disk), called crank, connected to a rigid bar,  called connecting rod. When rotating the crank, the connecting rod moves back and forward. The  rotation motion of a crank or crankshaft causes a rectilinear reciprocating motion of a piston or  plunger.  

It is a reversible system through which the connecting rod can be displaced by turning the crank and  the other way round. If the connecting rod generates the input motion (as a piston in a car's engine  does), the crank is obliged to rotate.  

This unit is supplied with the following manuals: Required services, Assembly and Installation,  Starting-up, Security, Maintenance and Practices manual.  

Experiments
Demonstration of the action of a simple crank and slotted link mechanism.  
Graphic determination of the relationship between the linear displacement of the sliding block  and the angular displacement of the input crank.
More advanced exercises may include the determination of the velocity and acceleration of  the slider block by graphical differentiation and comparison with the values obtained by  velocity and acceleration diagrams.
