For the beam and loading shown below, derive an expression for the reactions at supports $A$

and $B.$ Assume that $EI$ is constant for the beam.

For $EI=43000kN*m^2,L=4\mathrm{.}7m,$ and $w=11k\frac{N}{m},$ enter the values for the vertical

reaction forces $A_y$ and $B_y$ at supports A and $B,$ respectively. For $A_y$ and $B_y,$ enter a positive

value if the force acts upward on the beam, or a negative value if it acts downward. Also, enter

a value for the reaction moment at $B,M_B.$ Enter a positive value if $M_B$ acts counterclockwise

on the beam, or a negative value if it acts clockwise.
