Shear force in a beam experiment

this lab experiment is to determine the bending moment and the shear force on the beam. In addition, we evaluate how to develop a shearing force and the bending moment on a beam. Introduction: The aim of performing the experiment is to determine the bending moment and shear for at whichever section of the beam. In addition, it helps us to develop the association among the bending moment and shear force at different parts of the beam. Bending moment and shearing force are significant factors to consider while designing a structural component. In this experiment, we test a beam supported at two points with one end free and hang the weights from different sections of the beam. Shearing force is defined as an internal resistance developed in the beam cross section, so that the transverse external load acting on the beam is balanced. It acts as an unaligned force that balances the load that pushes in one direction and the shear force reacts at the opposite direction. Compression force occurs when the two forces are aligned into each other. On the other hand, bending moment is the rotational force that acts perpendicularly to the point at a particular distance away from the given point. This lab experiment is significant in that it enable the engineers to understand how shear force and bending moment impacts the material that are used for construction. Through distribution of loads on a beam one can observe the impacts on the beam at different points under different weights. Scope: The purpose of this lab was to measure bending and shear placed upon a beam. We tested a beam supported in two places with one free end by hanging weights from different parts of the beam. The shear and bending acting on the beam have been then determined from our detectors and calculations. Significance: This experiment is about the shear and bending moment and how they affect materials that engineers use and assign for specific buildings. This is important since it works by distributing loads on a beam in order to see how load could change the beam situation. By doing this, some values are produced such as experimental stress and parabolic tress. Shear and bending moment would give results about loads and it can occur in any compressive structure. Apparatus: • Clamps • Weight Hangers • Shear force apparatus • Weights • TQ test frame • Digital force display • Moment beam Procedure: Ensure the test frame is put on the working bench to allow easy access of the frame 1. Place the four securing nuts at the top of the frame to their estimated ultimate locations. 2. Allocate both supports of the apparatus to the test frame with four of the shorter thumb screws and the securing nuts. 3. Connect the digital force display to the bottom of the frame in the same way. 4. Use the supplied cable to fix the force sensor to the digital force display.
