ASSIGNMENT 3
This assignment is due by 5pm Friday 27th May, 2016.
QUESTION 1 (20 marks)
a) For the frame ABCDEF shown above draw the axial force, shear force and bending moment diagrams. Show all your working clearly and indicate the location and magnitude of the maximum bending moment on the appropriate diagram.
b) Determine the internal forces acting at B, C and E adjacent to the central joint. Use the results to show that the central joint is in equilibrium by drawing a FBD of it.
QUESTION 3
Using dM/dx = V draw the bending moment diagram for the beam from the shear force diagram shown below.
QUESTION 4 (32 marks)
(a) Draw all relevant internal action diagrams for the beam shown below. Determine the magnitude and location of the maximum bending moment and mark this on your diagram. Show all your working clearly.
(b) Draw all relevant internal action diagrams for the rigid frame ABC shown in Figure 4. Determine the magnitude and location of the maximum bending moment and mark this on your diagram. Show all your working clearly. Assume the joint at A is a pin and support C is a roller. The joint at B is fixed. The wind load is transferred to the members at the girts and purlins from the simply supported wall and roof segments.
