Chapter 3, Problem 20E

In order to determine the magnitude of the internal forces, a FBD must be cut. It is difficult to determine where a cut should be made in order to reveal the Maximum Internal Forces, thus we have put the distance to the cut in terms of 'x', and plot the equation. In my lecture we took a generic portion of a Beam and applied equilibrium and saw that Loading, Shear and Moment are related to each through differential equations. Change in Shear is the Area under the Loading diagram. Change in Moment is the Area under the Shear Diagram. Using Graphic Integration draw the shear and moment diagrams for the given beams and loading.

L by the double integeration method. E = 200 GPa , I = 20 X10ʻmm“, and L = 3.0 m._Extra points will be added if you also model it using RISA-2D software. Send me the model file, the deflected shape in a PDF file Compute the values of slope and deflection for the beam shown below at x = with the maximum deflection values, and a screenshot (image) for the deflection value at the pointL shown on the deflected shape. 350 KN/m 70 KN/m 400 KN.m
