If there is a uniformly distributed load due to gravity on a truss, how do I convert this into point forces on the three pin joints on the truss?

I am having trouble trying to work it out as I'm pretty sure there will be both forces in the x and in the y for each of the joints, but I can't work out how to determine this.

Thanks

Have you tried calculating the resultant force of the distributed force (which by the looks of your drawing will be at the middle joint, in the -y direction) and then calculated the forces in each truss due to the resultant force?

Remember, the moment caused by a distributed force can be expressed as a single resultant force applied at a point.
