When designing a structural member, which of the following statements is FALSE? A. The allowable stress is used in calculating the maximum load to be applied. B. The ultimate stress depends on the Factor of Safety used. C. The ultimate stress is determined based on the material used. D. The allowable stress depends on how conservative the design is. Which of the following is NOT a valid reason for increasing the Factor of Safety? A. Higher uncertainty in loading conditions B. Higher design life C. Lower confidence in assumed/stated material properties D. Lower member importance Consider a 1,000-mm long, 25-mm diameter sample subjected to a tension test. Automatic high-precision gages recorded that for an applied load of 150 kN, the sample experienced a longitudinal strain of 2×10−3mm/mm. Assuming that the material remained elastic while loaded, determine its modulus of elasticity.
