A
in. thick machine part supports an
end load of 1000 lb as shown in Figure P7–35. Determine the stress
concentration factors for the two changes in geometry located at the radii
shown on the lower side of the part. Compare the stresses you get to classical
beam theory results with and without the change in geometry, that is, with a
uniform depth of 1 in. instead of the additional material depth of 1.5 in.
Assume standard mild steel is used for the part. Recommend any changes you
might make in the geometry.
