Shear Force Apparatus Model MT 072

A length of material supported horizontally and carrying vertical loads is called a beam. The loading causes bending and transverse shearing. The loads and reactions are the ‘external’ forces acting on the beam. They must be in equilibrium. However, the strength of the beam depends on ‘internal’ forces. This experiment demonstrates the nature of these internal forces and their dependence on the external system of forces.
In the Sci-tech Shear Force Apparatus Model MT 072, the experimental beam is in two parts, joined by a pair of ball bearing rollers running in flat vertical tracks

Item Description

• Bench mounted
• Direct measurement of Shear Force
• Loads and supports can be placed in any position
• Visual practical verification of the concept of Shear Force
• Allows investigation of stability and influence lines
• Reinforces concept of equilibrium of vertical forces & moments

Technical Specifications

• To perform a range of experiments designed to both demonstrate and experimentally confirm basic engineering principles
• To observe the action of shear force at a section in a beam and to compare the measured and theoretical values
