1. A horizontal circular plate is suspended as shown from three wires that are attached to a support at D and form 30° angles with the vertical. Knowing that the z component of the force exerted by wire BD on the plate is 232.14 N, determine ( a) the tension in wire BD, ( b) the angles ux, uy, and uz that the force exerted at B forms with the coordinate axes.
2. A transmission tower is held by three guy wires anchored by bolts at B, C, and D. If the tension in wire AD is 315 lb, deter-mine the components of the force exerted by the wire on the bolt at D.
3. Knowing that the tension in cable AB is 1425 N, determine the components of the force exerted on the plate at B.© BrainMass Inc. brainmass.com March 4, 2021, 9:46 pm ad1c9bdddf
