1. Determine the shear force and bending moment diagrams for the beam in Fig. 1. (20%)Fig. 1

4. An overhanging beam ABC has a guided support at A, a rectangular cross section, and supports an upward uniform load q = P/L over AB and a downward concentrated load P at the free end C (Fig. 3). The span length from A to B is L, and the length of the overhang is L/2. The cross section has width b and height h. Point D is located midway between the supports at a distance d from the top face of the beam. Knowing that the maximum tensile stress (principal stress) at point D is σ1 = 38 MPa, determine the magnitude of the load P. Data for the beam are as follows: L = 1.75 m, b = 50 mm, h = 220 mm, and d = 55 mm. (20%)
