If the breaking point of a jack is 6,000 pounds, and the maximum expected load is 4,000 pounds, what is the safety factor?
What will be an ideal response?
S.F. = Ultimate stress (breaking point)/Working stress (maximum expected load)
S.F. = 6,000 pounds (designed capability)/4,000 pounds (maximum load rating)
S.F. = 1.5
