Problem 1: Solve the following three questions of the beam ABCD Note that A is a fixed end; B is a pin connection; C is a roller support; and D is a free end.

1) Draw the quantitative influence line for the vertical support reaction at point A;

2) Determine the maximum vertical support reaction that can be developed at point A in the beam due to: a concentrated moving load of SkN and a uniform moving load of 3kN/m;

3) Draw the bending moment diagram for the beam ABCD subjected to the loading obtained from 2). (The location and magnitude of the maximum bending moment must be calculated)

Problem 2: Solve the following two questions of the truss arch. Note that A and G are pin supports. The load is moving on the top chord only

1) Draw the influence lines for the force in bar DG.

2) If the truss is loaded by a uniform dead load of 5 kN/m over the entire length of the top chord, determine the magnitude of the bar forces in members DG.
