1. A screw-type jack is being used to raise one corner of a car with a flat tire. It takes 910 lbf to raise the tire off the ground. If the pitch of the threads is 0.375 inches and the lever arm is 14 inches, how much force (in lbf and N) must be applied? 6. How much power (in hp) is needed to move a 450 lb crate 100.0 ft vertically in 1.2 minutes?
