Q2. The pin-connected frame is subjected to the force Fas shown. The dimensions are 4-4.0 ft, - 2.6 ft. and -3.9 ft. Member BC is made of steel (E- 29000 ksi), and has rectangular cross-section, with b- 13 in. and h=4.1 in. The supports at B and Cact as pins for x-x axis buckling and as fixed supports for y yaxis buckling. Determine the greatest load F(in the unit of kip) the beam will support without causing member BC to buckle. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Your Answer:
