A rectangular bar is cut from an AISI 1020 cold-drawn steel flat. The bar is 2.5 in wide by 3/8 in thick and has a 0.5-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 nd = 2, estimate the largest force Fa that can be applied ignoring column action.
