Calculate shear force and bending moments with a UDL and a point load

Homework Statement

Bending Moments, Shear Force

Relevant Equations

Bending Moments, Shear Force

Hello,

I am looking for some help. I have completed the question below. I will show my answers.

My answer:

I believe this to be correct. If it is not would appreciate someone letting me know so i can correct.

Now i am attempting this question:

Could anyone help, or point me in the right direction so i can them calculate the point load?

I understand how it would look on the Shear force diagram. But not sure how to show the calculations, or calculate the bending diagram.

Any help much appreciated.

I am not sure I understand your concern. The shear and bending moment diagrams for the UDL case look good. For a point load at the center of the beam, 1/2 of the point load goes to each reaction . For the bending moments at the ends and center, you look them up in a table like you did for the UDL case. Then add 'em up for the total combined shear and moment (UDL plus Point Load).

Yes that is what i wanted to know.

Thank you for your help.
