Current Attempt in Progress

The toggle$-$wedge is an effective device to close the gap between two planks during construction of a wooden boat. For the combination shown, if a force $P$ of $310$ lb is required to move the wedge, determine the friction force $F$ acting on the upper end $A$ of the toggle. The coefficients of static and kinetic friction for all pairs of mating surfaces are taken to be $0\mathrm{.}46.$

Assume $=21,=3.$
