For the bottom diagram (the one with point and UDL loads) the FoS needs to be above 10 to meet the customer specification. What size would the beam need to be as a rectangular cross section? What is the minimum sized "I" beam to meet the factor of safety? Show workings (a spread sheet may be used) and then evaluate which is the optimum. Coefficient of linear expansion for steel = 11x10^-16 per °C. Modulus of elasticity for steel - 206GN/m^2. UTS of 400MN/m^2 300mm 20KN 10m 10m 200mm 2.5 kN/m 20KN 10m 2.5 kN/m 5m For the bottom diagram (the one with point and UDL loads) the FoS needs to be above 10 to meet the customer specification.
