Two blocks joined by a single pin are subjected to a pulling force of $P=300lb.$ The pin has a diameter of $0\mathrm{.}375$ in and the dimensions of the blocks with respect to the figure below are listed below.

$a=3\mathrm{.}32in$

$b=1\mathrm{.}77in$

$c=1\mathrm{.}74in$

$t_1=0\mathrm{.}67in$

$t_2=1\mathrm{.}26in$

Note that the dimensions $b$ and $c$ represent the distance from the edge of the block to the middle of the pin
