Question 1 In beam design, beams typically fail in three modes. From the list below, which one is NOT one of these modes? O Moment O Deflection O Shear O Fatigue Question 2 Allowable strength is typically a defined characteristic. Of the following equations, which one is used for calculating allowable strength? O allowable strength = failure strength / factor of safety O MR = 0.6SyZx O Zx = 1.67Mmax/Sy O Q = SHGF XAX SC x CLF Question 3 When failure is defined as the first yield in the structure, this is known as what type of design approach? O Load Resistance Factor Design O Inelastic Design Approach O Elastic Design Approach O Allowable Strength Design Question 4 When considering the bending moment in beam design the minimum required plastic section modulus must be calculated. Of the equations below, which is used to perform this calculation? O A = bh/2 O sb = M/S O Zx = 1.67Mmax/Sy None of the answers are possible
