The strut is supported by a pin at C and an A-36 steel (Young's Modulus is 200 GPa) guy wire
AB. If the wire has a diameter of 5 mm, determine how much it stretches when the distributed
load acts on the strut.
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.
