The cantilevered jib crane is used to support the load F. If the trolley T can be placed anywhere in the range x1 ≤ x ≤ x2, determine the maximum magnitude of reaction at the supports A and B.

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.

Units Used:

kip = 1000 lb

Given:

F = 780 lb

a = 4 ft

b = 8 ft

x1 = 1.5 ft

x2 = 7.5 ft
