Torsion and Deflection Testing Apparatus

Description of Torsion and Deflection Testing Apparatus

Torsion and Deflection Testing Apparatus allows a variety of experiments to be undertaken to investigate test specimens under torsional loading and bending loading within their elastic limits. The students cover topics involving bending moment equation, torsional rigidity, modulus of rigidity, angle of twist, and create graphs and compare actual measured values with theoretical values using formulae and theory provided. Torsion and Deflection Testing Apparatus extruded base frame carries two solid vertical supports. Profiled grooves within the base frame, fasteners and quick release handles ensure quick and easy adjustment of the span between the vertical supports.
