Jacob and Matthew Fast have just broken the record for the "Heaviest Vehicle Pulled Over 100 ft by a Male Pair". They are the sons of multiple record-breaking strongman Reverend Kevin Fast. They followed in their father's footsteps by pulling three fire trucks over 100 ft on flat ground. These fire trucks combined to weigh 86,350 kg or 190,400 lb.
After hearing that these brothers pulled this crazy amount of weight I wondered how much work they had done.
I initially looked up both the static and kinetic coefficients of friction. I then realized that overcoming the static friction occurs over such a small distance that the work done would essentially be zero. The kinetic coefficient friction = 0.8.
