Q$1-2(4$ pts$.)$

A simply supported beam with concentrated loads $(450N,300N$ and $700$ N $)$ and a moment of $1500N-m$ is shown below. Select the coni $t$ answer and show your work.

$$

Q$1.$ Magnitude of the resultant force, $F_R$

$F_r=\sqrt[\phantom{2}]{F_x^2+F_y^2}$

$F_x=450cos60-700sin30=-125N$

$F_y=-[45sin60+300+700cos30]=1295\mathrm{.}93N$

$F_r=\sqrt[\phantom{2}]{{125}^2+{12\mathrm{.}96}^2}=1301\mathrm{.}95N$

a$.1805$ N

$($b$)1302$ N

c$.2409$ N

d$.759$ N

c$.447$ N

a$.1805$ N

b$.1302$ N

c$.2409$ N

d$.759$ N

e$.447$ N

Q$2.$ Specify where the resultant force $(F_R)$ acts, measured from $B($to the right side$)$ if the $y-$components of the resultant force is $1296$ N downward

a$.2\mathrm{.}86$ m

b$.2\mathrm{.}42$ m

c$.1\mathrm{.}36$ m

d$.0\mathrm{.}84$ m

e$.0\mathrm{.}5$ m
