Question

Learning Goal: To determine the effects of certain geometric shapes, namely fillets and circular cutouts, on the stress distributions inside a rigid body and to determine the maximum applicable axial force in the same rigid body while considering these stress concentrations. The member shown below is made of steel ($\sigma_{allow} = 160$ MPa) that is 83.0 mm thick. The member is subjected to an axial force $P$ that is applied at both ends. Let $r = 25.0$ mm, $w = 100$ mm, $h = 50.0$ mm, and $d = 10.0$ mm. A) Determine the stress-concentration factor $K$ due to the 10.0-mm-diameter circular cutout in the member. Express the stress-concentration factor to three significant figures. $K = $
