Stress Ratio For each of Problems 1-9, draw a sketch of the variation of stress versus time, and compute the maximum stress, minimum stress, mean stress, alternating stress, and stress ratio, R. For Problems 6-9, analyze the beam at the place where the maxi- mum stress would occur at any time in the cycle. 6. A part of the structure for a factory automation system is a beam that spans 30.0 in as shown in Figure P5-6. Loads are applied at two points, each 8.0 in from a support. The left load F₁ = 1800 lb remains constantly applied, while the right load F₂ = 1800 lb is applied and removed fre- quently as the machine cycles. Evaluate the beam at both B and C. A 8 in F₁ = 1800 lb 14 in F2 = 1800 lb 8 in D RA B C 4X2X1/4 Steel tube Beam cross section RD
