A 50 lb sandbag is suspended by two ropes. Suppose that a three-dimensional coordinate system is introduced so that the sandbag is at the origin and the ropes are anchored at the points (0,−2, 1) and (0, 2, 1). (a) Assuming that the force due to gravity points parallel to the vector (0, 0,−1), give a vector F that describes this gravitational force. (b) Now, use vectors to describe the forces along each of the two ropes. Use symmetry considerations and draw a figure of the situation.
