THE FOLLOWING INFORMATION IS TO BE USED IN THE NEXT 2 (TWO) QUESTIONS. Twelve (12) lines are strung between the blocks in a frictionless block-and-tackle system of a drilling rig. The drilling line has a strength capacity of 120,000 lbf. Determine the travelling block velocity when hoisting a load of 330,000 lbf if the power at the drawworks is 2,000 hp. Determine the safety factor used if the maximum load that can be supported by the hook is 720,000 Ibf.
