Basic principles of torsion bar suspension used on army track vehicles are explained in the United States.

Explanation of the basic principles of torsion bar suspension. The vehicle suspension uses a torsion bar as the main weight bearing spring. United States tank destroyer 3-inch Gun Motor Carriage (GMC) M10 and 76 mm Gun Motor Carriage M-18 tank destroyer move along an uneven terrain. M-10 uses spring type suspension and M-18 uses torsion bar suspension. A man uses a model to describe the principles of torsion bar suspension used on army track vehicles. He uses a plain piece and a simple model for demonstration of principles. The bar's torsion resistance is demonstrated. Torsion bar and suspension bar are explained by the model.
