Question 7
Determine the smallest allowable cross-sectional area in square mililimeters of member BD of the truss shown below. The working stresses are 138MPa in tension and 83MPa in compression. Hint: Solve for internal force at CE and determine whether it is a tension of conpression (indicative of the conventional sign for normal force or axial force). Then, use the given applicable working stresses to solve for the minimum area required.
