Question

A beam subjected to axial loading will experience an axial stress, σa. If, in addition, the beam is subjected to a bending load, a bending stress, σb, will also occur at the outer fibers (top and bottom surfaces) of the beam. The maximum stress at the outer fibers of the beam will be σmax = σa + σb. Assume that σa and σb are independent. Given: σ̄a = 95 MPa, σ̂a = 8.6 MPa, σ̄b = 385 MPa, and σ̂b = 22.5 MPa. The rod is made of steel with S̄ = 553 MPa and σ̂s = 42.7 MPa. Assuming the strength and stresses have normal distributions, determine the design factor and the reliability guarding against yielding. The design factor is [ ]? The reliability guarding against yielding is [ ]?
