The barge B is pulled by two tugboats A and C. At a given instant, the tension in cable AB is 5,000 lb and the tension in cable BC is 2000 lb. Determine by trigonometry the magnitude and direction of the resultant of the two forces applied at B at that instant. Two ropes are attached to the barge at point B. The other ends of the ropes are attached to the tugboats at points A and C.Two ropes are attached to the barge at point B. The other ends of the ropes are attached to the tugboats at point A, 30 degrees above the horizontal up and to the right from point B, and point C, 45 degrees below the horizontal down and to the right from point B. The magnitude of the resultant is 5846.056 lb. The direction of the resultant is ⦨ °. (Round the final answer to two decimal places.) 的热门建议 |
