    The beam OA carries a load P and is supported by two cables as shown. Knowing that the tension in cable AB is 732 N and that the resultant of the load P and of the forces exerted at A by the two cables must be directed along OA, determine the tension in cable AC, resultant and the load P.


    [IMAGE: A 3D figure with x, y and z axes. Beam OA lies along the x direction from O to A, with load P acting at A. Cable AB runs from A to support B and cable AC runs from A to support C. Dimensions marked: 580 mm, 500 mm, 860 mm and 720 mm [unclear which dimension belongs to which segment].]

  1. 2082 ChaitraChapter 2: Forces Acting on Particle and Rigid Body2.3 Principle of Transmissibility and Equivalent Forces

    Replace the given force of 800N at E with an equivalent system consisting of a vertical force at A and second force at D.


    [IMAGE: An L-shaped body. The horizontal bottom member carries points A, B and C with dimensions 1 m, 1 m and 2 m along it. A vertical member rises with point D at mid-height and point E at the top, with 1 m between E and D and 1 m between D and the bottom. An 800 N force acts at E directed upward and to the right at 60 degrees to the horizontal.]
