gear ratio formulas: Ouput Torque = Input Torque x Ratio of Gear Reduction Torque is measured in Inch Pounds Output Speed = Input Speed / Ratio of Gear Reduction Example: A gear reducer with 1000 in/lbs of input torque, an input speed of 2000 RPM, and a reduction ratio ,

Risk Ratio For the study examining wound infections after incidental appendectomy, the risk of wound infection in each exposure group is estimated from the cumulative incidence The relative risk (or risk ratio) is an intuitive way to compare the risks for the two groups

I know that forging reduction ratio is defined as the ratio of the original to the final cross-sectional area However, I've recently encountered the suggestion that if an ingot is upset to increase the cross-sectional area before being forged to reduce the cross-sectional area, the reduction ratio is the ratio of the upset cross-sectional area to the final cross-sectional area
