Question

2. State Any Assumptions. Analyze the Frame Structure below by setting up Free Body Diagram and a Torque Diagrams for Pivots at the Fixed Supports only. Develop the Equations. Do Not Solve. Hint: Make sure to reveal any other Forces aside from the 12 kN force. Hint: Realize that a frame reacts as one structure. Hint: If needed, Remember that Sin is Opposite/Hypotenuse and Cos is Adjacent/Hypotenuse. 0.6 m OE 0.9 m - 0.9 m2 0.3 m

State Assumptions Show all work. Circle final answer. Please include units. Please state assumptions where appropriate.
