Step-by-step explanation:

Next, we shall study how to draw the influence line diagram for shear force in a simply supported beam. For description we take the same beam and the same point P as in Example, for which we now proceed to draw the shear force influence line diagram.

Example

Draw the influence line diagram for shear force at point P in the simply supported beam AB of span 10 m. P is 4 m from the hold up A.

Solution

Let us assume that the moving unit load is at a distance x from A. the reactions RA = 10 - x /10, and RB= x/10 as determined earlier.

Case (a) : If the unit load is between the points A and P, then considering forces to left of P,
