The bell crank lever trainer (SM – 005) is designed to determine the reaction force of a bell-crank lever to an applied load. The bell crank lever enables the reaction force of a 90° bell crank to be measured by a spring balance when a load is applied at any of five leverage ratios.
- A sturdy aluminum base frame supports a vertical pillar onto which pivots the bell crank lever.
- The bell crank lever contains five loadings rings into which the load hanger can be fitted to vary the mechanical advantage of the system.
- A spring balance is supported horizontally at the base of the bell crank lever, and has an adjustable mechanism to enable the datum position to be returned.
- A set of calibrated weights is supplied with the unit along with a comprehensive instruction manual.
