The heavy-duty box-section support beamworks as the main support underneath the test beams and the leaf spring duringthe tests. The spring is of the same heavy-duty design as those used in vehicle suspensions. The Beam and Leaf Spring parts fit into the compressive testarea of Universal Testing Machine. The testing machine applies a compressive bending force and measures the beam deflection. Students may adjust the position of the knife edge supports to setthe length of beam under test. This give students a better understanding of a ‘real world engineering component. For beam tests, the test beam rests across two knife edge supports fixed to the support beam. This forms a ‘simply supported beam. For leaf spring tests, the spring rests on its rollerson two fl at supports fixed to the support beam. They can then compare theresults with those predicted by theory. Again, the testing machineapplies a compressive force and measures the leaf spring deflection. For thebeams, students use the deflection and force values to find the relationshipbetween force and deflection for the different beams.

A flexible beam is supported between two end brackets which create simply supported end conditions. One end bracket allows pivoting only whilst the other allows rolling and pivoting only. Experimental module, which fits into the Vibration Frame making up part of the Universal Vibration Apparatus. The vertical brackets and standard length beam are both supplied. One of the brackets is supported on vertical supports that can be moved depending on the beam length being used.
The Beam Bending Vibration Module is forced to vibrate using a motor exciter. This allows high rotational speeds to be achieved. A speed sensor on the motor exciter monitors the speed of rotation of the eccentric masses and outputs Beam Bending Vibration Module. The motor exciter is supplied as standard and has two eccentric masses attached directly to the motor spindle at either end. This motor exciter can be attached anywhere along the beam length between the brackets.
