Description
This apparatus represents the forces in a simple crane and introduces the student to equilibrium of forces and solution by the triangle of forces. The crane is mounted on a base designed to be stood on a level bench. The jib arm pivots about its vertical support, whilst the tie retains the jib in its angled position. Both the jib and tie include spring balances for measuring the internal forces. A load is hung from the end of the jib by using the Load hanger and calibrated weights set provided. Readjustment of the crane geometry back to its original unloaded layout is possible by adjusting the links of the chain.
