Diego Reyes 2. The rigid pipe is supported by a pin at B and an A36 steel wire connected between points B and D at point C. The wire has a diameter of 0.375 inches. For the load shown, the tensile force in the guy wire is 3606 lb. Determine the stress in the cable (in ksi) and verify that it is less than the yield stress for A36 steel (oy=36 ksi). If Hooke's Law applies, determine the elongation of the wire in inches. E 30 x 103 ksi 3 ft B Solution.
