A 21.0-kg floodlight in a park is supported at the end of a horizontal beam of negligible mass that is hinged to a pole as shown in the figure below. A cable at an angle of e = 31.0 with the beam helps support the light. A (a) Draw a force diagram for the beam. |Choose File | No file chosen This answer has not been graded yet. (b) By computing torques about an axis at the hinge at the left-hand end of the beam, find the tension in the cable. N (c) Find the horizontal component of the force exerted by the pole on the beam. magnitude direction ---Select--- (d) Find the vertical component of this force. magnitude N direction ---Select--- Now solve the same problem from the force diagram from part (a) by computing torques around the junction between the cable and the beam at the right-hand end of the beam. (e) Find the vertical component of the force exerted by the pole on the beam. magnitude IN direction ---Select--- (f) Find the tension in the cable. N (g) Find the horizontal component of the force exerted by the pole on the beam. magnitude IN direction --Select--- v (h) Compare the solution to parts (b) through (d) with the solution to parts (e) through (9). Is either solution more accurate? O Solution using torque about hinge is more accurate. O Both solutions are equally accurate. O Solution using torque about hinge is less accurate.One end of a uniform 3.90-m-long rod of weight F. is supported by a cable at an angle of @ = 370 with the rod. The other end rests against the wall, where it is held by friction as shown in the figure below. The coefficient of static friction between the wall and the rod is u. = 0.525. Determine the minimum distance x from point A at which an additional object, also with the same weight , can be hung without causing the rod to slip at point A. B A m Need Help?
