Hey. Im currently doing a course in numerical analysis, and while most of the focus is on the mathematics side of things, the assignments are set in an engineering context. One of my assignments describes a beam that is "pin jointed" at both ends, is 1 meter long, and is subject to a 0.5 N/m uniform load upwards from one end to 0.3m into the beam, and then for the remaining 0.7m is subject to a 1 N/m uniform load downwards. Here is the diagram ive drawn: http://img16.imageshack.us/img16/1130/beamu.th.gif [Broken] I am required to calculate the reaction forces. I actually study chemical engineering, so i haven't really dealt much with beam mechanics since my first year introductory courses. I think i have solved it, but i'd really appreciate it if somebody could verify whether my solution is correct or not. http://img11.imageshack.us/img11/1289/30115449.th.gif [Broken] So both my reactions are vertical with the magnitudes as specified above. Have i done that correctly? Thanks in advance, any help is greatly appreciated. Dan.
