Reaction of Beams Apparatus (SMT-MM-19)
Determination of the reaction forces in the supports
of a simple supported beam under various loadings,
also measurement of loads and moments on a lever,
validation of the principal of equilibrium.
The apparatus consists of a beam of approximate 1m
long, linear spring balances, three load hangers, and
a bench top mounting unit.
Technical manual for student and lecturer provided.
1m ruler supplied.
Set of weights.
A horizontal length of material with a vertical load system is called a beam. It is one of the
most basic engineering ways of supporting a load. External forces such as the applied loads
and the beam support reactions have to be in equilibrium. Given a loading system, the
support reactions can be calculated from force and moment equations. This apparatus is
designed for simple experiments and demonstrations on simply supported beams. Two
spring balances act as supports and enable reactions to be read directly. Three movable load
hangers allow loads to be put in a number of positions.
