Draw a FBD of the beam with reactions at A & B. A is a pin, B is a roller. Try to guess intuitively which way the vertical c

omponents of A & B are pointing. Do not show the 6 kN forces in your FBD. Only show the couple moment, or pure moment

Answer:

kindly check the drawing of the FBD of the beam with reactions at A & B. A is a pin, B is a roller in the attached picture.

Explanation:

Without further ado, let's dive straight into the solution to the question above. From the diagram of the FBD of the beam with reactions at A & B it can be shown that the reaction moment is anticlockwise while the moment is clockwise.

The system is at equilibrium and the it does not matter where you place the couple (pure) moment.

The distance from A to C can either be equal or not. If AY = 2.15 kN and M = 25.8. Then, the distance between A and B = 25.8/2.15 = 12m.
