Part B $-$ Analyzing the force$-$couple system on a bracket

For the bracket shown below, $F_1=132lb,F_2=44lb,$ and $M=500lb-$ ft $.($Figure $2)$ Replace this force and couple system with an equivalent force by specifying the magnitude of the force, the di

force acts, and where the force's line of action intersects member $AB$ as measured from $A.$

Express your answers, separated by commas, to three significant digits. The angle should be measured counterclockwise from the positive $x$ axis $($parallel to segment $CB).$

Part D $-$ Analyzing a system of forces acting on a concrete slab

The concrete slab shown in the picture is subject to four forces, $F_1=240lb,F_2=345lb,F_3=555lb,$ and $F_4=240lb.$

The dimensions are $d_1=9\mathrm{.}0ft,d_2=19ft,d_3=3\mathrm{.}5ft,d_4=14ft,$ and $d_5=8\mathrm{.}5ft.$

Determine the equivalent resultant force by specifying its magnitude and its location $(x,y)$ on the slab.

Express your answers, separated by commas, to three significant figures.
