Compound Bar (Brass and iron, 200 x 25 mm, reverted, with wooden handle)

This compound bar consists of brass and iron strips laminated together and fixed to a wooden handle, allowing students to observe unequal expansion when heated. As the metals expand at different rates, the bar visibly bends—demonstrating the principle of thermal expansion coefficients
