1. By how much will the clamping force on the joint be reduced? Sketch the new joint diagram, assuming maximum initial preload? Compute the estimated maximum bolt tension and minimum clamping force under the 3,000 lbs external load
2. Does the addition of the external load endanger the bolt? Sketch an alternate form for joint diagram for this situation? Define the ‘‘critical external load.'' Approximately what would you expect it to be for this joint?
