Unformatted text preview: welded together at B and are supported by three wires. Knowing that a = 1.25 ft, determine the tension in each wire. (This problem is on equilibrium in 3D. We will look at this on Monday.) Problem #4: Eight identical 20 X 30-in. rectangular plates, each weighing 50 lb, are held in a vertical plane as shown. All connections consist of frictionless pins, rollers, or short links. For each case determine whether (a) the plate is completely, partially or improperly constrained, (b) the reactions are statically determinate or indeterminate, (c) the equilibrium of the plate is maintained in the position shown....
