The solid bar $AB$ is clamped between rigid points A and $B.$ The bar has a constant section area of A and Modulus of Elasticity of $E.$ Take $L=8$ feet.

Force $P=12$ kips applies at distance $a=3\mathrm{.}0$ feet from support $A.$ The reaction force at support $A$ is most nearly:

$8\mathrm{.}57$ kips

$5\mathrm{.}83$ kips

$12\mathrm{.}0$ kips

$9\mathrm{.}14$ kips

$6\mathrm{.}86$ kips

$7\mathrm{.}50$ kips
