Features

• Conversion of rotary motion into oscillatory motion1 
• Demonstration of the principle of axle pivot steering

Tesca Four Bar Chain demonstrates rotary motion is converted into oscillatory motion. An anodized aluminum disc is mounted on ball bearings as a crank. The disc has a scale so that the input angle can be exactly measured. The crankpin can be set at different radii on the disc.
The connecting rod and the oscillating lever, made of black anodized aluminum, can be connected together in different lengths using easy-to-fit knurled bolts. The oscillating crank is attached to a disc with an angle measuring scale. All components are fitted to a white plate fitted with plastic feet. The unit is placed on the laboratory table for the experiment. Two metal handles make the unit easier to carry.
