Question
Q 3\ A rectangular bar is cut from an AISI 1018 cold-drawn steel flat. The bar is 60 mm wide
by 10 mm thick and has a 12-mm hole drilled through the center, k,-0.899, k,=0.85.
Su 440MPA, Sy-370Mpa, K-2.5, q-0.82, The bar is concentrically loaded in push-pull
fatigue by axial forces Fa, uniformly distributed across the width. Using a design factor of nf
= n, = 1.8, estimate the largest force Fa that can be applied ignoring column action.
