A rectangular bar is cut from an AISI 1020 cold-drawn steel flat. The bar is 2.500 in wide by 4/8 in thick and has a 0.500-in-dia. hole drilled through the center as depicted in Table A-15-1. The bar is concentrically loaded in push-pull fatigue by axial forces Fa, uniformly distributed across the width. Using a design factor of na = 2, estimate the largest force Fa that can be applied ignoring column action. What is the largest force that can be applied to the part? (Round the final answer to three decimal places.) The largest force that can be applied is kips.

Using a design factor of na = 2, estimate the largest force Fa that can be applied ignoring column action. What are the values of the theoretical stress-concentration factor, the notch sensitivity, and the fatigue stress-concentration factor? The value of the theoretical stress-concentration factor is The value of the notch sensitivity is (Round the final answer to three decimal places.) The value of the fatigue stress-concentration factor is (Round the final answer to three decimal places.)

! Required information A rectangular bar is cut from an AISI 1020 cold-drawn steel flat. The bar is 2.500 in wide by 4/8 in thick and has a 0.500-in-dia. hole drilled through the center as depicted in Table A-15-1. The bar is concentrically loaded in push-pull fatigue by axial forces Fa, uniformly distributed across the width. Using a design factor of na = 2, estimate the largest force Fã that can be applied ignoring column action. Determine the endurance limit for this material as well as the value after correction for surface finish, sizing, and loading. The endurance limit for the material is kpsi. The endurance limit after correction is kpsi.

A rectangular bar is cut from an AISI 1018 cold-drawn steel flat. The bar is 1 in wide by 3/8 in thick and has a ¼ in-diameter hole drilled through the center. The bar is subjected to a tension load fluctuating between 800 and 3000 lb. estimate the factors of safety guarding against failure by yielding and by fatigue action. (Assume infinite life is desire)
