Transcribed Image Text: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 (oallow = 140 MPa ) that is 55 mm thick. The member is subjected to an axial force P that is applied at both ends. Let rf = 15 mm , w = 100 mm ,
h = 50 mm , and d = 20 mm
