# Beam Reactions

I need help with this problem:

You have a beam and this is the information I have and I need to find the reaction [ascii art is hard]

50 kip

V
----------------------------
| | | | | | | | | |
V V V V V V V V V V
---------------------------- <---- 4 kips/ft
^ (-)
/_\ (_) <---that is a circle
|----10 ft---|
|------------20-------------|

^Ra ^Rb

I need to solve for Ra and Rb, it would be very much appreciated if someone could walk me through the steps also.

Thanks!

EDIT: the art doesn't work so I will tell you, there is a triangle at the left [Ra] end and a circle at the right [Rb] side.

Sorry, but I am still not sure of what you are trying to draw. Try it using the "code" brackets:

[ code ]

[ /code ]

(without the spaces)

What that does is it preserves spaces that you put in the text, like so:

Code:
I'm writing on the left.
Oooh, now I'm writing on the right!

Code:
