NORTH SHORE, PGH – Dovetailing off of last Wednesday’s post, today we will look at how much force is applied, relative to pounds, when a bat makes contact with a baseball.
Looking at these numbers from, Dr. Daniel A. Russell, Professor of Acoustics at Penn State, a peak force of 8,314 pounds is generated each time a MLB player hits a home run.
According to researchers at Liverpool University, when a Tyrannosaurus Rex brought its jaws together, it could create a force of 13,000 pounds. That amount surpasses that of all animals, both living and extinct, including the Nile Crocodile, whose bite has been measured at 5,000 pounds, the Great White Shark which provides a force of 3,600 pounds and the African Lion which comes in at 1,235 pounds of force.
With these comparisons, we can see just how violent an action it is when bat meets ball at the professional level. In terms of SwingTracker, the ability to measure Barrel Speed and Impact Momentum gives a good indication of the exit speed of the ball as it’s leaving the bat – part of the equation (F avg = m v f – m v i Δt) that applies in terms of calculating force generated by a home run, relative to pounds.
Tomorrow we will continue with a deeper dive into the science behind the swing.
