TM 415 BEAM APPARATUS
TM 415 BEAM APPARATUS
This beam apparatus is of a universal design for use in a wide range of beam experiments with simple, built-in and sinking supports measuring of, point loads, support reactions and beam deflections.
The beam frame consists of a stainless steel angle upper cross member and two aluminum profile lower cross members, bolted to the support columns with footings. Three spring load cells with height adjustment and a cantilever support can slide along the lower members and can be clamped at any point. Dial indicators can slide along the upper member and can be clamped at any point. Linear scale is attached to the upper member to indicate the positions of load cells, loads, supports and dial indicators.
The spring load cell has a hardened steel tube sliding in a bushing with hardened steel knife edge on top of the tube. The tube rests on a coil spring on a lead screw which provides direct load reading via a dial indicator. The height of the knife edge can be fixed at any position by a wing bolt.
