$1.$ Beam AB is subjected to the two distributed loads shown in the figure below:a$)$ Replace each of the distributed loads with a single equivalent point load and sketch the result on a $1800$ N$/$m complete free$-$body diagram of the beam.Clearl

yindicate both the magnitude and location of each equivalent point load. $(6$ points$)$

B$)$ Given your results of part a$),$ determine the reactions at A and B$.(4$ points$)$
