Yesterday people could try themselves in a new sports amusement in Moscow. Anyone who agreed to pay 100 rubles (about 3 USD) and could hang for 2 minutes on the bar were promised to be given 1000 rubles (about 30 USD)… But people were not warned that the bar could rotate on its axis…
l – eccentricity
p – weight
The force applied to the cylinder with the eccentricity makes it revolve. The heavier your body is the harder it becomes for you to hold the bar. Forearm muscles do not endure the tension for two minutes. Profit!
