4. Two links made of heat treated 6061 aluminum (Sy = 276 MPa, Sys = 160 MPa) are pinned
together using a steel dowel pin (Sy = 1398 MPa, Sys = 806 MPa) as shown below. The
links are to support a load P with a factor of safety of at least 2.0. Determine if the link will
fail first by tearout, direct shear of the pin, bearing stress on the link, or tensile stress at
section AA. (Hint: find the load P for each case and choose the case that gives the smallest
load.)
