Consider the frame pictured below:

a$)$ Draw a Free Body Diagram of the entire frame and use it to solve the reactions at D$.$

b$)$ Split the frame apart at the pins and draw a Free Body Diagram of each component of the frame.

c$)$ Use your FBDs from b$)$ to calculate the x and y components of the force from each pin $($A$,$ B and C$).$
