 TM 115 Forces in a Crane Jib
 Technical Description

TM 115 represents a planar central force system in which multiple forces act on a single point of application. Based on the example of a crane jib, forces are determined graphically and experimentally: resultant cable force, tensile force, compressive force. The directions and magnitudes of the forces are determined graphically by way of a force parallelogram.
A bar of adjustable length and a chain make up the crane jib, which is attached by adjustable clamp elements to a retaining bar. A variety of jib forms can be created. Loads are applied to the crane jib. The occurring bar forces are indicated by integrated spring balances.

Learning Objectives / Experiments
- Graphical breakdown of forces by force parallelogram
- Determination of the bar forces on various jib forms
- Comparison of: measurement result - calculation - graphical method
