DescriptionA sturdy aluminium base frame supports a vertical pillar onto whichpivots the bell crank lever. The bell crank lever contains five loadingsrings into which the Load hanger can be fitted to vary the mechanicaladvantage of the system. A spring balance is supported horizontally atthe base of the bell crank lever, and has an adjustable mechanism toenable the datum position to be returned. Lever mechanisms of allshapes and sizes are very common parts of machines, particularly inhand operated devices. The bell crank lever offers the typicalmechanical advantage of a lever, and in addition it turns the line ofaction of the effort through 90°. In most cases the cranked lever wouldbe a casting with a bushed pivot at the corner. The experimental modelhas been built up from plastic to simulate the real thing. This traditionalitem enables the reaction force of a 90° bell crank to be measured by aspring balance when a load is applied at any of five leverage ratios.
