    ASSIGNMENT 6: CHAPTER SIX (DUE 28/10/20)

    A steel rod of cross-sectional area 600 mm2 and a coaxial copper tube of cross-sectional area 1000 mm2
    are firmly attached at their ends to form a compound bar. Determine the stress in the steel and in the copper
    when the temperature of the bar is raised by 80°C and an axial tensile force of 60 kN is applied.
    For steel, E = 200 GN/m2 with 𝛼 = 11 x 10-6 ℃
    For copper, E = 100 GN/m2 with 𝛼 = 16.5 x 10-6 ℃

    ASSIGNMENT 7: CHAPTER SEVEN PART 1 (DUE 04/11/20)


    1. Sketch the S.F. and B.M. diagrams for the beam in Figure 6.

    Figure 6

    2. A beam 4.2 m long overhangs each of two simple supports by 0.6m. The beam carries a uniformly
    distributed load of 30 kN/m between supports together with concentrated loads of 20 kN and 30 kN at
    the two ends. Sketch the S.F. and B.M. diagrams for the beam and hence determine the position of any
    points of contraflexure.

    ASSIGNMENT 8: CHAPTER SEVEN PART 2 (DUE 11/11/20)


    A cast iron beam has a cross-section as shown in Figure 7. The
    beam is simply supported on a span of 8 m. The beam carried
    a uniformly distributed load of 1.5 kN/m length on the entire
    span. Determine the maximum tensile and compressive
    stresses.

    ASSIGNMENT 9: CHAPTER EIGHT (DUE 18/11/20)


    An elemental cube is subjected to tensile stresses of 200 N/mm2 and 120 N/mm2 acting on two mutually
    perpendicular planes and a shear stress of 80 N/mm2 acts on these planes. Determine the magnitudes and
    directions of the principal stresses and the greatest shear stress using both analytical and graphical methods.

    ASSIGNMENT 10: CHAPTER NINE (DUE 25/11/20)


    A hollow shaft has to transmit 6 MW at 150 rev/min. The maximum allowable stress is not to exceed 60 MN/m2
    nor the angle of twist 0.3° per metre length of shafting. If the outside diameter of the shaft is 300 mm, find
    the minimum thickness of the hollow shaft to satisfy the above conditions. G = 80 GN/m2.
