Moment at a point applied to a bracket

  1. Sep 13, 2013 #1
    1. The problem statement, all variables and given/known data
    Calculate the magnitude of the force supported by the point at A under the action of the 2.5-kN load applied to the bracket. Neglect friction in the slot.

    AB = .17 m

    B to force = .16 m

    angle between vertical and BtoForce = 24


    3. The attempt at a solution

    I found the x and y distance of the force from B

    y = .16 cos 24 = .1462

    x = .16 sin 24 = .0651

    I tried multiplying the force by the y distance but it was incorrect.

    I also found the distance from A to the force which is:

    √((.17 + .0651)2 + (.1462)2) = .2768

    and multiplied that by the force but that was also incorrect. Any ideas?

    Any help appreciated!

    I think you must make a FBD of the bracket. Because there is no friction in the slot, any reaction at B must be perpendicular to the surface of the slot. Write your equations of equilibrium about pin A and solve.
