## Homework Statement

The beam ABC in attachment has a pinned support at A and Roller supports at B and C. P is an internal pin. I have to determine the reactions at A, B and C and at the pin P when the beam is loaded as shown in the attachment

## Homework Equations

[tex]\Sigma[/tex]V=O [tex]\Sigma[/tex]H=0

## The Attempt at a Solution

I have split the problem in half and started with the right hand side. I have worked out the reaction at the pin as +4.00 kN and the reaction at C as +6.00 kN. I have done this by taking the moments of P as (10x3)-VC*5=0. I then worked out the sum of the vertical which = 0 to get the reaction at the pin that was VP-VC-10= 0 meaning that VP =+4.00 kN. I have worked out the horizontals on the left by doing the sum of the horizontals = 0, [tex]\Sigma[/tex]H=0

=HA-15cos60=0 HA= +7.5kN. What I would like to know is how to find out the vertical reaction at A and B Thanks
