DESCRIPTION

The beam specimens are made from either aluminium or stainless steel and are 20mm wide with either a thickness of 3 or 5mm.

Three different types of support are supplied with the experiment. The first of which is a simple support that is capable of measuring the reaction force at the support as well as being able to act as a sinking support. The second support can be used in either a fixed configuration where a clamping plate holds the beam in place, simulating a fixed support or by removing the clamping plate, the support can be used to simulate a simple support. This support also has the capability to measure the reaction force acting at the support.

The final support is a support that is able to measure the fixing moment due to the fixed support.

Point loads are applied to the beam through either two point load hangers or a UDL sleeve in combination with the two 500g slotted weight hangers. The point load hangers can be moved along the length of the beam allowing many different loading conditions to be explored.

The slotted weights supplied and the weight hangers can be used inside the UDL sleeve to simulate a UDL load applied to the beam. The UDL sleeve has a central access point allowing the beam deflection to be accurately measured.
