Question

0 You, the best engineer in A, B, or C) in an old roof truss at a client's ho has a weight of 200 lbs. It is estimated that all truss members have a tensile and a compressive (buckling) strength of 250 lbs. Assum positive and negative x directions and roller 2 can resist directions. Wh your design firm, are asked by your boss to determine a location (point use in the figure for hanging a crystal light which strength of 300 lbs e roller 1 can resist forces in both forces in both positive and negative y ommend? Your answer needs to be ich locations (point A, B, or C) you will not rec justified

Explanation / Answer

There is only one location that shoul not be recommended. That location is B .This is because if you take a closer look at the truss,it is more like a beam with internal hinge at B. If we apply a concentrated load at B, the truss will see hight deflection.aslo,the forces in members will be high.
