Can you answer choosing the pipe size of the column?
A free standing jib crane similar to one shown is to be designed for a capacity of 3 tons. The load can swing through a full 360 degrees; L=10ft., b=8.5ft., c=2ft. The moment on the jib is balanced by a couple Q?Q on the post, the forces Q acting at supporting bearings. The crane will be fastened to the floor by 6 equally spaced bolts on a 30 inch bolt circle, the outside diameter of base is 36 inches. a) Choose a pipe size for the column such that the maximum stress does not exceed 12ksi. b) Choose an I-beam for the jib such that the maximum stress does not exceed 12 ksi. c) Compute the maximum external load on a base bolt and decide upon the size. d) Complete other details as required, such as calculating Q and choosing bearings (ball or roller), the design in the bearing area, and all other details such that a jib crane could be manufactured from your drawings. e) Use SolidWorks to produce an assembly drawing with parts list attached. Use an FEA analysis in SolidWorks or Ansys to verify your hand calculations. f) Submit report at or before the due date.
