4) Use a cross product to find the area of the triangle whose vertices are the points P(1,0,0), Q(0,2,0) and R(0,0,3). 5. (Section 13.4 problem 52 of our text) A horizontally outstretched arm supports a weight of 20 lb in a hand (see figure). If the distance from the shoulder to the elbow is 1 ft and the distance from the elbow to the hand is 1 ft, find the magnitude and describe the direction of the torque about (a) the shoulder and (b) the elbow. (The units of torque in this case are ft-lb.)
