Description

The beam used in this experiment has been split into two sections and then re-joined to allow the shear force and bending moment to be measured at the point the beam has been split. The connection of the two sections of beam allow it to be adjusted so that the sections are parallel and level, using the supplied level, while allowing the beam to be deflect under load.

The split beam rests on two simple supports, one at each end. Each beam section rests on a roller that is free to rotate allowing the beam to move as it deflects. The simple supports are fixed laterally through slots in two universal frame mounts allowing the position of the simple support to be adjusted.

The side plate of each support can be used as a pointer against the tape measure fixed to each beam section, allowing the position of the supports relative to the split to be recorded.

Point loads are applied to the beam through three extended weight hangers and three 1000g slotted weight hangers. The extended weight hangers can be moved along the length of the beam allowing many different loading conditions to be explored.

Like the simple supports, the extended weight hangers have a pointer that may be used against the tape measure fixed to each beam section, allowing the position of the supports relative to the split to be recorded.
