A beam is composed of two channels, C 811.5, as shown in the following figure. The beam is supported at the left end by a in- round eye bar. A % in pin is used at each eye. The beam is supported at C by a steel bearing plate measuring 4inx6in, which rests on a concrete wall. Determine the maximum load W that can be applied. The allowable stresses are as shown below. Assume the beam to be strong enough to carry the load. [1] Allowable stresses: Shearing stress in the pin=10,000 psi Concrete bearing stress-500psi Tensile stress in the rod-18,000psi Steel bearing stress-45,000 psi NOTE: the web thickness of a C 811.5 channel is 0.220 in HE Two C 8 x 11.5 A B 2' C + 8' W A beam is composed of two channels, C 811.5, as shown in the following figure.
