Problem #1 through #5 will be completed by hand on a piece of paper. Please complete the problem by printing the prepared exam calculations sheets (otherwise complete problems on your own sheet of paper) (this is the document found under the starter question), scan your solutions, and submit one (1) cohesive PDF of all problems, in-order, to the Canvas Online Exam under the starter question. Problem #1 – Stress and Strain Analysis (20 points total, 3 parts) An 18-foot-long structural steel bar is tensed along its centroidal axis. Point B is being tensed by 127 kips of force and point C is being tensed by 87 kips of force. The bar has a square cross-section with a base and height of 2.7 inches. The steel is ASTM HSLC steel with a yield stress, σy = 50 ksi and modulus of elasticity, E = 30,000 ksi. Show all work and any assumptions clearly. Record your answers on the answer key. Complete the following: Part A (8 Points): Calculate the axial stress in sections AB and BC of the beam. Does the calculated stress in either section exceed the yield stress of the steel? Part B (8 Points): Calculate the deformation in sections AB and BC of the beam. What is the total axial deformation that the beam experiences? What is the final length of the beam? Part C (4 Points): Calculate the factor of safety that this structural bar was designed for.
