Prоblem #2 thrоugh #6 will be cоmpleted by hаnd. Pleаse complete the problem by printing the prepаred 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 #2 – Stress and Strain Analysis (15 points total, 3 parts) A 20-foot-long structural steel bar is tensed along its centroidal axis. Point B is tensed by 47 kips of force and point C is tensed by 147 kips of force. The bar has a rectangular cross-section with a base of 1.8 inches and height of 3 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 on the provided calculation sheet. Record your answers on the answer key. Complete the following: Part A (6 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 (6 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 (3 Points): The allowable stress in the beam is 29.9 ksi, calculate the factor of safety the beam was designed for.
