Now consider the diagram of a different simply supported beam shown in Figure P11. The dimensions of the beam may be different to the previous questions.

A triangular distributed load (w₃) is applied between point B and point C

,

varying

linearly from zero at B to a maximum at C, as shown. The beam span between A and D is as shown on the diagram. 

Which of the following correctly identifies the value of x (in m) where x  is the point of application (distance from A

)

of the equivalent resultant force

Assume the load acts vertically downward and varies linearly as shown in the figure.

Figure P11b. The point of application of the equivalent resultant force F_EQ due to the triangular distributed load, x (in m), measured from point A
