Chapter 5, Problem 37P
The cantilevered jib crane is used to support the load of 780 lb, if. x = 5 ft. determine the reactions at the supports Note that the supports are collars that allow the crane to rotate freely about the vertical axis. The collar at B supports a force in the vertical direction, whereas the one at A does not.
