Express your answers in newtons to three significant figures. Enter your answers separated by a comma. ▾ View Available Hint(s) ▾ Hint 1. How to approach the problem We should use equilibrium equations for the member. Consider forces acting on the member. Note that the support at A allows free translation along the z axis. You will get the system of three equations which could be solved for components of reactions. ▾ Hint 2. How to express the components of the tension force The tension force is directed along the cable, therefore components of the force are equal to the product of magnitude of force and the unit vectors for the cable.
