A beam is supported by a roller at point A and a pin at point B$.$ Three forces are applied on the beam.

Values for the figure are given in the following table. Note the figure may not be to scale.

$\backslash$table$[[$Variable$,$Value$],[F_1,3$ kN$],[F_2,2$ kN$],[F_3,2$ kN$],[d_1,1\mathrm{.}5$ m$],[d_2,2\mathrm{.}5$ m$],[d_3,5$ m$],[{}_1,25$ degrees$]]$

a$.$ Replace the force system with an equivalent force, $F_R.($enter the magnitude$)$

b$.$ Determine the direction of the resultant force $F_R,$ measured counter$-$clockwise from the negative $x-$axis in degrees. Answer must be between $090$

c$.$ Replace the force system with an equivalent couple moment acting at point $B,M_B.$

Round your final answers to $3$ significant digits$/$figures$.$

$F_R=$

$=$

$M_B=kN$
