Question $1$

A $4\mathrm{.}8$ m long beam is subjected to the forces shown where F$1=278N,F2=669N,F3=183N,$ and F$4=413N.$ Reduce the system of forces to an equivalent force

and moment at A$.$ What is the sense and magnitude of the equivalent force? Include a negative number if your answer is directed downward and a positive number if

your force is directed upward. Express your answer in Newtons.
