PROBLEM A uniform horizontal beam

$5\mathrm{.}00$ m long and weighing $3\mathrm{.}00\backslash$times $10^(2)$N

is attached to a wall by a pin connection

that allows the beam to rotate. Its far

end is supported by a cable that makes

an angle of $53\mathrm{.}0\backslash$deg with the horizontal

$($Fig$.8\mathrm{.}18$a$).$ If a person weighing $6\mathrm{.}00\backslash$times

$10^(2)$N stands $1\mathrm{.}50$ m from the wall, find

the magnitude of the tension vec$($T$)$ in the

cable and the components of the force

vec$($R$)$ exerted by the wall on the beam.
