Free response 15. A loaded cement mixture drives onto an old igure P11.52 draw bridge where it stalls with its center of 70 gravity three-quarters of the way across the span the truck driver radios for help, and waits. - 10.0m Meanwhile a boat approaches, so the prints ro al drawbridge is raised by means of as cable attached to the end opposite the hinge, as SupTo 40.0 m shown. The mass of the drawbridge is 18,000 do 30 kg and its center of gravity is at its midpoint. The cement mixture with driver has mass mulemom islugns to rollsvisenos 30,000 kg. When the drawbridge has been raised to an angle of 30 above the horizontal, the cable makes an angle 70 with the surface of the bridge.ing a) What is the tension, T on the cable when the drawbridge is held in this position? 2.84 105 N b) What are the horizontal and vertical components of the force the hinge exerts on the span. 2.18 105 N, 2.88 105 N
