Scenario: You are changing a car tire and need to use one of the 2 options below to exert force on the tire iron to loosen a tight lug nut (need the lug nut to spin counter clockwise, so toward the ground). Which option has the potential to create the most force in a single blow?
-the action is being performed by someone physically able to effectively perform both options mentioned below. -the tire iron can be set to whatever angle makes the most sense for each option (might make more sense to be parallel to the ground for option 1, but at a more acute angle for option 2).
Option 1: While standing on top of the tire iron, which is firmly covering the lug nut and setup to be parallel to the ground, jump straight up in the air and land on the tire iron while accelerating your feet in a downward motion.
Option 2: Instead of relying on your body weight falling, this option relies more on building/releasing energy like that of a proper baseball swing, a punch or certain karate kicks. For this option you setup the tire iron so the end of the handle, the end furthest away from where it actually hugs the lug nut, is angled down closer to the ground rather than completely parallel (to make the area on the tire iron we are attempting to strike more easily accessible). Then, facing the side of the car and standing a few feet left of the tire/tire iron, you side step towards the tire as fast as possible while attempting to create additional energy by picking up your right foot, leaning on your left foot, and then exploding towards the tire iron by pushing off your left foot and swinging your hips as much as possible. You transfer that energy with the completion of the kick/stomp with your right foot.
Option 1 seems like the 'common sense' answer, but I sometimes find your average person doesn't consider/acknowledge the amount of energy you can build up/transfer without the use of gravity. Since I don't have the means to calculate rough estimates myself I figured I'd ask for help here.
