Problem $8\mathrm{.}54$

$($C$)2$ of $4$

Two blocks A and $B,$ each having a mass of $5$ kg $,$ are connected by the linkage shown in $($Figure $1).$

Part A

If the coefficients of static friction at the contacting surfaces are ${}_B=0\mathrm{.}8$ and ${}_A=02,$ defermine the largest vertical force $P$ that may be applied to pin $C$ without causing the blocks to slip. Neglect the weight of the links. Express your answer to three significant figures and include the appropriate units.
