Task 1 - Analysis of a truss for deflection The truss shown in Figure 1 carries a load of 'P' kN Analyze the truss system using the unit load method and determine the deflection at the node C for the given loads. Consider E = 210 kN/mm²; I = 60X106 mm4, A = 200 mm². A F E P KN |x3| t-x1 x2. B Figure 1 Truss Identify the zero force members and discuss how the members play a role, if any, in the stability of the truss with proper justification.

For the beam shown: (a) determine the distance a for which the maximum positive and negative bending moments in the beam are equal; and (b) draw the corresponding shear and bending moment diagrams for the beam.

Two line loads q1 and q2 of infinite lengths are acting on top of an elastic medium, as shown in Figure P8.6. Find the vertical stress increase at A.

A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 45 ft-kips, and the maximum moment for the service live load is 63 ft-kips (these moments occur at the same location on the beam and can therefore be combined). a. If load and resistance factor design is used, determine the maximum factored bending moment (required moment strength). What is the controlling AISC load combination? b. What is the required nominal moment strength for a resistance factor of 0.90? c. If allowable strength design is used, determine the required moment strength. What is the controlling AISC lead combination? d. What is the required nominal moment strength for a safety factor of 1.67?
