You, the best engineer in your d A, B, or C) has a weight of 200 lbs. sign fim, are asked by your boss to determine a location (boint a client s house in the figure for hanging a crystal light which nated that all truss members have a tensile strength of 300 lbs strength of 250 lbs. Assume roller 1 can resist forces in both sign firm, Ibs It positive and negative x directions and roller 2 a will not re oand roller 2 can resist forces in both positive and negative y ustified 4, B, or C) you will not recommend? Your answer needs to be

Explanation / Answer
