TITLE OF EXPERIMENT:
REACTIONS OF SIMPLY SUPPORTED BEAMS
DATE PERFORMED:
13TH OF AUGUST 2008.
AIM:
I) TO DETERMINE THE REACTIONS RA AND RB FOR A BEAM SIMPLY SUPPORTED AT ITS ENDS
II) TO DETERMINE THE VALUES OF RA AND RB AS A GIVEN LOAD MOVES FROM ONE END OF A SIMPLY SUPPORTED BEAM TO THE OTHER
APPARATUS:
• Two spring balances. • A steel beam of hollow section. • Load hanger. • Load / weights ranging from 2kg to 10kg. • Meter rule. • Inextensible cord.
THEORY
A beam with a constant height and width is said to be prismatic. When a beam’s width or height (more common) varies, the member is said to be non-prismatic.
Horizontal applications of beams are typically at resists the rotation.

TYPES OF LOADS AND BEAMS
Beams can be catalogued into types based on how they are loaded and how they are supported. Loads that are applied to a small section of the beam are simplified by considering the load to be single force placed at a specific point on the beam. These loads are referred to as concentrated loads. Distributed loads (w, usually in units of force per lineal length of the beam) occur over a measurable distance of a beam. For the sake of determining reactions, a distributed load can be simplified in to an equivalent concentrated load by applying the area of the distributed load at the centroid of the distributed load. The weight of the beam can be described as uniform load. A moment is a couple as a result of two equal and opposite forces applied at certain section of the beam. A moment induced on any point can be mathematically described as a force multiplied by at one end and simply supported at the other (see figure 2d). A continuous beam has more than two simple supports, and a built-in beam (see figure 2f) is fixed at both ends.
