At Reedy, the invite guys are getting from maybe 10 mph coming through the esses to 50+ at the end of the straight less than 120 feet away. I'd like to know what kind of g forces these cars pull under acceleration. As far as damage to humans, I believe human factor engineers typically use 3g forces as an upper limit for tolerable acceleration, say when designing a roller coaster. Different assumptions will give different results. These values yield a constant acceleration through the turn of 24.6 meters / second^2Įxpressing that value in multiples of the car’s weight, you divide by the acceleration of gravity, yielding ~2.5g forces. Lane width of typical indoor track = 10 feet = 3.048 metersĪssumed constant radius of turn (perhaps a 180 degree turn heading onto the straightaway) = 6 feet = 1.83 metersĪssumed constant velocity of stock motor TC navigating this turn = 15 mph = 6.71 meters / secondĪcceleration of gravity = 9.81 meters / second^2 You can use whatever values you feel comfortable with to compute an answer. If you’re interested in lateral acceleration, and you assume that the car is traveling at a constant speed through a constant radius turn, you only need the equation for centripetal acceleration (constant velocity circular motion): (velocity) * (velocity) / (radius). Slow day at the office today and my colleagues and I are having a discussion about 1/10 TC and what sort of G forces are developing as the car accelerates/brakes and takes corners.Īssuming you had a 1/10th scale person in the car what effects would these g-levels have on the person other than presumably a horrible death?Īs I said slow day in the office. Any physicists out there with some math ability?
