Unit for studying Forces in a Jib Crane

The Unit for studying Forces in a Jib Crane is designed to study the tensile and compressive forces in a planar central force system based on the example of a jib crane.

The unit represents a planar central force system in which multiple forces act on a single point of application. It consists of a bar of adjustable length (compression jib) and a chain (tension tie), which is adjustable, and both incorporate a spring balance to measure the bar forces in them. The compression jib and the tension tie make up the jib crane, which is attached by adjustable clamping elements to a retaining bar.

A weight holder and a set of weights apply loads to the jib crane through the junction of the compression jib and the tension tie.

Based on the example of a jib crane, forces are determined experimentally, theoretically and graphically: resultant cable force, tensile force and compressive force. The magnitudes and directions of the forces are graphically determined with a force parallelogram.
