Extracted text: Description: Abeam is simply supported and carries the load shown in Figure 1. 1. Calculate the reaction forces at pointA and C. 2. Draw the complete shearing force and bending moment diagrams. Specify the maximum bending moment. 3. Specify suitable dimensions for the beam, if it is steel and the allowable normal stress is 100 MPa, for the following cross section shapes: (a) Square (a rectangle with height=width) (b) Rectangle with height three times the width (c) Rectangle with height one-third the width (d) Solid circular section 4. Which shape should be selected if the requirement is minimum material consumption ? 30 kN 25 kN А В D 1,5 m 1 m 1 m
