Bending moment is a rotational force that occurs when force is applied at any place away from at any point perpendicularly. A bending moment will occur when a moment is applied to a system so that the system will bend. According to Hibbeler, beams develop different internal shear force and bending moment from one point to another along the axis of the beam due to applied loadings. A bending moment experiments may be vary according to experiments. The moment is calculated and measure as force times distance of the force applied to the pivot point. As a result, the bending moment will have newton-metres (N.m) as its unit.
The aim of the experiment is to understand the concept of the structural engineering studies in simpler way, which is through an experiment. At the end of the experiment, the bending moment at any given point along a simply supported can be calculated. How the loading of given set of condition could affect the bending moment also can be understand at the end of the experiment.
Observation & Results
There were 2 different experiment was conducted to observe the bending moment. The first experiment, Experiment 1, is to observe the bending moment at a given point using different set of weight and also to calculate the percentage error between the experimental value of the bending moment and the theoretical value of the bending moment. In second experiment, Experiment 2, the purpose is to observe how the bending moment varies at the cut when different loading conditions on the simply supported beam.
The experiment started with setting the digital force display to zero. Place 100g mass to a hangar. Then place the hangar on the plastic bar below the cut. Record the reading on the digital force display, which is the experimental shear force. Repeat using 200g, 300g, 400g and 500g of
