Question 1: For the truss below, using the method of joints: a) Calculate the degree of static indeterminacy for the truss (SI) and state if the truss can be solved using only equilibrium. b) Find the member forces in all the members and clearly indicate if they are in tension or compression. Note that some of the truss is already solved including member forces and a reaction. You may identify any zero-force members directly on the diagram below. c) Neatly complete a summary diagram showing calculated member forces, force arrows, and reactions. Do this on a new figure you are to draw at the end of the problem. 2m 5 kN 2m 2m 2.5 kN (C) 3.536 kN (C) 2m 5 kN 2m E RE=2.5 kN /10
