structural question please HELP!! Hi all, new to this physics forum business. I am wondering if anyone can tell me how to find reaction forces in a structure where there is more than two supports. I am familiar with the conventional method of taking the moment about a point to find one reaction, and then summing forces in the y direction to find the other. But I am unsure where to start if there is more than two unknowns. Please see the example I have attached.
