Question details

Problem Consider a simply-supported beam P/2 P/2 subjected to four-point bending as shown. For this beam, the length L-4m and the offset from the support to the load a-75cm. The total force P-6.4kN. The beam has a rectangular cross-section with a height h -80mm and a width w- 25mm, and is made of a material with an elastic modulus E-150GPa. (a) D raw the shear and moment diagrams for the beam. (b) Using the conjugate beam method, determine the deflection of the beam at midspan and the rotation of the beam at supports A and D (b) Determine the bending stresses at the top and bottom of the cross-section. (c) Determine the normal strains at the top and bottom of the cross-section.
