I am supposed to draw a shear force diagram of the loading shown. I used hypothetical number. This is what I did and for some reason its not coming out right.

The shear at the right hand side of the beam should be zero. Because the reaction is 3/2 kips upward and the shearing due to the distributed load is -2 and 3/2 right before you account the upward right-most reaction, it does not go to zero. Please check this for me and tell me where I went wrong. Thganks


EDIT: the length of the entire beam is 2ft. and the 1 kip load is at midspan. I calculated the reactions here. I figured they are equal due to symmetry.

 

I can help you but I need you to explain the problem better. What is it that you expect (the solution) and what are you getting?

 

 

Haven't had to do a shear diagram since sophomore year in college - 14 years ago.

It looks like it should be +3/2 at the start, -1/2 at midspan, and -3/2 at the end. With an end reaction of +3/2, the -3/2 from the load should cancel out. I think.
