VandM functions SSCL C M D C 01

A beam is loaded and supported as shown, with $F_1$ = 2290 lb, $F_2$ = 2020 lb, $M$ = 6340 ft*lb, and $w$ = 1150 lb/ft.

The dimensions on the figure are a = 4.2 ft, b = 9.8 ft,and c = 3.5 ft.

Develop expressions that describe the shearing forces and bending moments in the beam as functions of x.

Reactions:
$R_B$ =
$R_D$ =
include units with your answers for reactions

Functions:
Interval 0 < x < 4.2 ft:
V(x) = lb and M(x) = ft*lb

Interval 4.2 < x < 14 ft:
V(x) = lb and M(x) = ft*lb

Interval 14 ft < x < 17.5 ft:
V(x) = lb and M(x) = ft*lb
omit units from the expressions you develop
