Identify the support reactions on the beam shown in $($Figure $1).$ A

is a pin and B

is a roller.

Check all the possible support reactions on the beam, even if some of them are equal to zero due to the loading given. Make sure the reactions in the set you choose do not depend on each other.

$$An $8$ meter long beam extends horizontally rightward from a pin supported end labeled as $\text{'}$A$\text{'}$ to a roller supported end labeled as B$.$ A uniformly distributed load of $75$ newtons per meter acts vertically downward on the beam between points $\text{'}$A$\text{'}$ and B$.$ A moment of $800$ newton meters acts clockwise around end B$.$ The x y plane is shown. The x a xis is directed to the right, and the y axis is directed upward.
