Please help me calculate the force I use when I do pull-ups
Suppose you do a pull-up for two seconds (neither fast nor slow), and then pull-up for one second, in which half a second accelerates at a constant speed and half a second decelerates at a constant speed. Use force to calculate the maximum strength, so calculate the force when accelerating uniformly. One arm is 50 cm long and the other half is 25 cm long. If you accelerate evenly for half a second through a distance of 0.25 meters, the acceleration is 2 meters per square second. To overcome the earth's gravity of 10 meter per second, the actual force on two arms is 80 * (2+ 10) = 960 N, and that on one hand is 480 N. If it is done quickly, it may be a little bigger.
I have forgotten a lot of old knowledge. If I am wrong, don't laugh at me.
