This compound bar consists of two metals, fitted to a wooden handle. On heating, the strip bends in a particular direction thereby showing unequal expansion of the metals, therefore demonstrating the physics of thermal expansion.
Dimensions: Total length with handle 9 ½”. Compound Bar only 5 ¼”x 1”
