Final answer:
To determine all the member forces in problem 2.15, you need to find the lever arms of the forces acting on the stick and use Newton's laws to calculate the applied force and resolve the components of the given forces.
Step-by-step explanation:
The question asks to determine all the member forces in problem 2.15.
The solution involves finding the lever arms of the forces acting on the stick and using Newton's laws to calculate the applied force and resolve the components of the given forces. By substituting the values into the appropriate equations, the magnitudes and directions of the forces can be determined.
