Eight identical 20 30-Ã— 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, answer the questions listed in

Prob. 4.61, and wherever possible, compute the reactions. Problem 4.61: The bracket ABC can be supported in the eight different ways shown. All connections consist of frictionless pins, rollers, or short links. In 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. Also wherever possible, compute the reactions assuming that the magnitude of the force P is 100 N.
