Recently, i read a car manual about changing a tire on my vehicle. it recommended using 100 ft·lbs of torque to tighten the bolts that hold the tire in place. i could use a torque wrench which measures the amount of torque applied when tightening a bolt. if the wrench i use is 40 cm long and i push on the very end of it, how much force, in newtons, must i use if the force i apply is perpendicular to the wrench?
