"Find reactions at A and B. Draw a FBD and the positions for all forces, check for equilibrium."
For this I have got to the conclusion of A + B = 8kN (assuming the plank is in equilibrium). As the 8kN force is closer to B, the force here will be greater. 2 forces will be shown at A and B, both pointing upwards at the points. Does the fact the B is on a roller joint affect the direction of the force at B? And what is the approach to finding out reactions A & B.
Also, how do you check for equilibrium?
Thanks for any help in advance.
