Question

determine the horizontal and vertical components of reaction at the pin a and the reaction of the rocker b on the beam.

Answer 1

Answer:

See explanation

Explanation:

Since no figure was given, I'll explain how to theoretically solve this problem.

When a pin is resolved it has 2 reaction forces, one in the horizontal direction and one in the vertical. For this problem you could name these Ax and Ay. These two forces will act where the pin is, with Ax acting in the horizontal direction and Ay acting in the vertical.

When a rocker is resolved, it has one reaction force that acts perpendicular to the surface the rocker is on. This force can be thought of as B and it acts where the rocker is.

If you are determining the value of Ax, Ay, and B you should use static equilibrium and data given on the figure to solve for the reaction forces. The equations for static equilibrium (2D) are $\sum Fx=0$,$\sum Fy = 0$, and $\sum M = 0$.
