Description
Technical Details

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.
