Basic structural learning begins with an analyzing of a simply supported beam. A beam is a structural member (horizontal) that is design to support the applied load (vertical). It resists the applied loading by a combination of internal transverse shear force and bending moment. An accurate analysis required in order to make sure the beam is construct without any excessive loads which affect its strength.

A bending moment exists in a structural element when a moment is applied to the element so that the element bends. Moments and torques are measured as a force multiplied by a distance so they have as unit newton-metres (N·m). The concept of bending moment is very important in engineering (particularly in civil and

When force is subjected further on the perpendicular distance from the origin, more bending moment are produce. This can be proven by equation below:

Moment = Fd

F = Load applied d = Perpendicular distance

2. When there is a moment produced, shear force will balance the system(moment & forces exist) so that it will be in equilibrium state. The amount of shear force(in equilibrium) can be measured by hanging few load to get both lines(moment indicator & shear indicator) in one line.

3. In engineering we need less amount of bending moment because it can reduce the amount of deflection in the beam. This can decrease the percentage of failure of the beam

Conclusions In this experiment, both bending moment and shear force need to be considered to make the system in equilibrium position. We also conclude that the shorter the perpendicular distance to the load, the system will produce less
