Member AB is supported by a cable BC and at A by a square rod which fits loosely through the square hole in the collar fixed to the member as shown in (Figure 1). Suppose that F₁ = 150 N, F₂ = 400 N, and the rod holds in equilibrium. Figure 3m A th F₁ 1 m B 1.5 m 1 of 1 Part A Determine the components of reaction force at A using scalar notation. 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.
