Q1 (8 Points): Consider the truss structure shown below which is composed of three members of different areas. This truss is loaded with a rightward facing horizontal point load at Joint C. 20' P 15' B 5' Member AB, Area = 1.2 in² Member BC, Area = 2.1 in² Member AC, Area = 2.7 in² (a) What is the maximum amplitude of the point load at Joint C such that stress in each truss member remains under 50 ksi? (Hint: Solve for the axial force in each truss member in terms of P.) (b) At the maximum load amplitude found in Part A, what is the stress in each member? (Hint: One of the stresses should be 50 ksi)
