AI Thread Summary
To solve the problem of determining reactions at the supports of an indeterminate beam structure, it's essential to apply the three equations of statics effectively. The presence of more than three reactions indicates that the structure is indeterminate, requiring additional equations to solve. A suggested approach involves taking moments about the hinge between the beam and the load, focusing on the inclined member and its reaction components. This method helps establish a moment equation that can assist in finding the unknown reactions. Understanding the role of the hinge in providing additional equations is crucial for solving the problem accurately.

Homework Statement



In the enclosed picture is a loaded beam and strut, what I need to do is determine the reactions at the supports. The problem is that I think the beam is indeterminable because there are more than three reactions?

Homework Equations



I do no the three equations of statics but don't no how to apply them in this context


The Attempt at a Solution



Could someone give me a hint in the right direction as to how to go about solving this problem?

Thanks in advance
James

Another picture hopefully the right way round :-)

Sorry don't no why this is uploading the wrong way round. The reaction supports should be on the left side.
 
The hinge between A and the load gives you another moment equation which yields one more equation. So, take moments about this hinge, but just for the inclined member and its reaction components. In other words, the bending moment at the hinge is zero in the inclined member, but not in the vertical member.
