Show transcribed image text 1-20 A beam subjected to axial loading will experience an axial stress, sigma a. If, in addition, the beam is subjected to a bending load, a bending stress, sigma b, will also occur at the outer fibers of the beam. The maximum stress at the outer fibers of the beam will be Assume that and are independent and The rod is made of a steel with MPa. Assuming the strength and load have normal distributions, determine the design factor and the reliability guarding against yielding.
During a test of a metal bar, it was found that a axial tensile force of 10,000 lbs resulted in an elongation of 0.023 in. The bar had these original dimensions, length 10 in. diameter 0.750 in. Compute the modulus of elasticity of the metal. What ki..

Do this by assuming uniaxial tension along [110] and expressing σ 1, σ 2,.. .,τ 12 in terms of σ [110]. Then use the matrix of elastic constants to ?nd e1, e2, . . .,γ 12, and ?nally resolve these strains onto the [110] axis to ?nd e[110].
