Question

Part A - Stress-concentration factor due to a circular cutout
Determine the stress-concentration factor K due to the 10.0-mm-diameter circular cutout in the member.

K=?

Part B - Stress-concentration factor due to the shoulder fillets
Determine the stress-concentration factor K due to the 15.0-mm-radius shoulder fillets in the member.

K=?

Part C - Maximum applicable axial force P
Using the information obtained about the stress-concentration factors in the member, determine the maximum applicable axial force P that can be applied to the member.

P=?

Part D - Maximum applicable axial force P without the circular cutout
Using the information obtained about the stress-concentration factors in the member, determine the maximum applicable axial force P that can be applied to the member if the circular cutout is not present.

P=?

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 = 145 MPa) that is 51.0 mm thick. The member is subjected to an axial force P that is applied at both ends. Let r = 15.0 mm, w = 80.0 mm, h= 50.0 mm, and d= 10.0 mm.
