[3]. (3 marks) Consider the following eccentrically loaded bolted connection. The resulting stress in the bolts is due to both shear and tension. There are 2 rows of bolts and each row has 2 bolts and the load $F$ passes through the centroid of the 4 bolts. If the bolts are $3/4$ in -10 ( $3/4$ in diameter and 10 threads per inch), having a tensile stress area of $0.334\mathrm{in}$, an allowable tensile stress of $20,000\mathrm{psi}$, and an allowable shear stress of $11,000\mathrm{psi}$, determine the maximum load $F$ that can be safely applied. As shown in the sketch, the stress due to bending and shear occurs in the threaded portion of the bolt. Assume a factor of safety of 1.5 .
