The pratt truss below supports a roof with a factored load of p = 40 k. a. indicate which members are in tension and label their required strengths in kips. show that you can compute the loads by hand, but feel free to check your work using analysis software. b. based on gross yielding alone, design the diagonal tension members as a36 angle sections (fy = 36 ksi, fu = 58 ksi), selecting the lightest possible l4×4 member for each. c. using a single line of 1/2" bolts spaced at 2" on center, compute the number of bolts required for each member such that the gross yielding design strength is less than the net section rupture design strength.
