Break-down torque ratio
WebThe breakdown of torque usually shows that only 10% of the input torque is useful. The rest is used up by friction. For example, underhead torque represents 50% of the input torque and thread torque is 40%. Hence, … WebNov 3, 2016 · To do this, you'd take two times Pi (or 3.141593) which equals 6.283186 feet. Take 220 feet and divide by 6.28 and we get an RPM of 35.014 for each revolution. Take the 150 feet and multiply times 35.014 and you get 5252.1 – which is our constant that is factored into measuring foot pounds of torque.
