A. Introduction:

It is important to know how the shear forces and bending moments vary along the length of a beam that is being designed. Graphs are used to describe the change of shear forces and moments. These graphs are called shear and moment diagrams. Employing these diagrams, the maximum and minimum shear and moment are easily identified and located.
Constructing shear and moment diagrams is similar to finding the shear and moment at a particular point on a beam structure. However, instead of using an exact location, the location is a variable distance 'x '. This allows the shear and moment to be a function of the distance, x.
In theory, this appears to be simple, but the equations can be complex, especially with distributed loads that are also a function of the location, x. Also, if there are multiple loads or supports, more than one function must be developed, for example one shear and moment function for each section or span of the beam.
When constructing shear and moment diagrams, the sign convention is important so viewers will know what direction the beam is bending or shearing. Generally, it is assumed that a positive moment causes a beam to bend downward and a positive shear will skew the beam with the left side going up and the right going down.

    The shear stress distributing in a beam depends on how Q/b varies as a function of y1. For a beam with a rectangular cross sectional area, subjected to a shear force V and a bending moment M. as a result of the bending moment a normal stress is developed on a cross section, which is compression above the neutral axis and it is tension below the neutral axis. To investigate the shear stress at a distance y1 above the neutral axis. Then dA=bdy, so equation 2 becomes…

    The member forces of a truss can be calculated if 2J=M+R where J is the number of joints, M is the number of members, and is the number of reaction forces. It will only be stable if this equation is true for the values of J, M, and R in a given truss follow the equation. If 2J is greaer or less than M+R, then the truss will be…

    First of all, values of deflections (δv, δh) were calculated for various head angles and loads as shown in Table 1-8. These deflection values were plotted against Load and gradients of the graphs of δv/W and δh/W were found out for various angles as shown in Figure 1-8 and stored in table 9. A graph was plotted between δv/W and δh/W which results in a circle. From the circle, values of offset and radius were used to calculate Principal second moments of area and orientation of principal axes.…

    The theory is that the stress in the bar is uniaxial with the principal stresses being equal to P/A and zero. The strains are biaxial with the maximum being P/AE and the minimum being – νP/AE. The first principal stress and strain will be aligned with the force and the long axis of the bar.…

    A tensile test was performed on a 4140 steel sample and the axial and transverse strains were measured. Data points were collected at incremental loads and graphed to determine the elastic modulus (30.4 x 106). Poisson’s ratio was also calculated from the dataset and determined to be 0.29. These experimental values agree closely (within 2%) to the textbook values of the steel sample. A sample of 7075 Aluminum was used in a cantilever beam test. Intermediate and end loads were place on the sample and the strain was measured at various distances from the loads. Using the dataset from the individual loads, the superposition strain was calculated and agreed within 7% of the experimental strain with both loads. From the measured deflection of the cantilever beam and the dataset, Young’s Modulus for the aluminum sample was determined to be 9.1x106 psi which agrees within 8% of the textbook value.…

    An investigation into beam bending and superposition. Being able to analyse how beams bend is an essential tool for all engineers. By using mathematics and material properties, engineers are able to compute structural deformation thus verifying a structures fitness for use. In this experiment a simply supported beam of aluminium is loaded with point forces in three different cases. A clock gauge is positioned in the middle of the beam to measure the deflection. The results of a complex arrangement of forces can be deduced by the superposition of more simple cases. Superposition is possible only when the response of the structure is linear, e.g. when deflection is directly proportional to the applied load. Also the experimental and theoretical deflections of the beam will be compared and a percentage error obtained. There was a second test performed in this investigation demonstrating the influence the 2nd moment of area, also known as the second moment of inertia, had on the load carrying capacity of the beam. The results from test 1 show that it is possible to deduce the deflection of the beam when loaded with point forces by superposition. Results from test 2 show that the deflection of a beam is influenced greatly by its moment of inertia, i.e. with a greater value of inertia there is a smaller deflection.…

    In this experiment we tested the deflection of a beam when it is placed with its widest and shortest side of its cross section on the supports. In order to examine the deflection of the beam, we applied the load at the center of its length. In addition, observing the deflection on the beam, we wanted to observe if the behavior of the deflection would be different when the position of the beam changed. After conduction the experiment we conclude that when the beam is positioned with its widest side on the supports, deflection happens faster and as more load is applied the deflection increases.…

    The loading beam (Silicon Carbide) is lowered at 10mm per second onto the plate. The load is applied until the glass breaks against the two supports (also of Silicon Carbide). The values for maximum load and deflection are recorded from the apparatus. Steps 1-4 are repeated for ten different samples. With a piece of emery paper scratch the surface of the glass slides along the width in the centre on one side only of a glass sample (see Figure 2)…

    Shear stress is a measure of a load on specific area, however differently from tensile stress, shear stress acts coplanar to a material cross section instead of acting perpendicular to the cross section. It is defined as force per unit area just like tensile strength and has the same units. Units: Pa.…

    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.…
