http://imageshack.us/photo/my-images/853/bridgel.png/ I don't answers course just some guidance. I need to find the forces at each joint, and stresses inbetween too. I've calculated the reaction forces by taking moments as 779N at far left and 692.5N at far right. Now I'm using trig of course to start from the left and work across finding the stresses but I have forgotten how to find the forces at each joint, and I'm not confident my stresses accurate. Could someone point me in the right direction then I can do the rest. Sorry if my drawing is poor, or if any other info is needed just say Thanks in advance.
