Problem 1: The beam shown below is loaded by two total distributed loads on both sides (30 kN on top side and 30 KN on bottom side). Draw the shear-force and bending moment diagrams. Neglect the mass of the beam. 0.4 m 1.2 m 0.4 m 30kN 30kn [20]
Problem 2: 300 mm A high strength steel belt, 20 mm wide by 0.80 mm think, runs over a pulley of 600 mm in diameter. a) What is the maximum flexural stress developed? b) What is the minimum diameter of the pulley that can be used without exceeding a flexural stress of 400 MPa? Assume modulus of elasticity equal to 200 GPa. 20 mm ITU 0.80 mm [15]
