The next two questions pertain to the situation described below. M O A vertical telephone pole of mass M 170 kg and height H = 17 m is braced with two wires that run between the pole and the ground as shown in the figure (the wires and the pole lie in the same plane). Wire 1 makes an angle 01 34° with the pole and is attached at the top. Wire 2 makes an angle 02 24° with the pole and is attached a distance h 12 m above the ground. The tension in wire 1 is T = 1500 N. 02 H T T h wire 2 wire 1 А 22) What is the direction of the torque exerted on the telephone pole by Wire 1 about an axis perpendicular to the page that goes through point A at the bottom of the pole? a. Perpendicular to the plane of the page, pointing out of the page. (b. Perpendicular to the plane of the page, pointing into the page. c. Along the direction of Wire 2, pointing up and to the left. 23) The tension T2 in wire 2 is chosen so that the total torque around Point A is zero. What is the magnitude of the (vertical] force that the pole exerts on the ground at Point A? a. 4795 N b. 3912 N c. 3128 N d. 4673 N e. 5580 N !!! 240 17
