(30), the portion of the shaft to withstand the torque, the portions of the first and second disc spaced along the shaft in the operating position of the portion connected to the shaft; and a sensor (64 , 66) assembly having a relationship with the first and second disk, to detect ...

(i.e., Power = torque × crank angular velocity). Thus, our results surprisingly showed that the agreement between the two devices for measuring cadence is very weak (r = −0.253 andp< 0.05). Moreover, PowerTap and Power2Max underestimated peak cadence measurements compared to the cadence...
Considering the relationship between torque and power, if we know the rate of rotational speed, otherwise known as the angular velocity, we can calculate power. Power is (force × distance)/time. Consider a bicycle crank arm that goes through one complete revolution in t seconds. Assume a ...
This chapter describes the basic concepts as well as the various methods and apparati in current use for the measurement of torque and power; the measurement of speed, or more precisely, angular velocity, is discussed elsewhere [1]. 展开 ...
The purpose of this study was to investigate the relationship between the isokinetic parameters of peak torque PT, work, and power for the extensor muscle groups of elderly female. The main aim was to ascertain how the angular velocity can affect the relation between peak torque, average power ...
Initially, the analysis was realized with only water, evaluating the torque for different angular velocities in the Brunswick Bioflo/CelliGen 115 bioreactor, using various impellers. However, it was not possible to measure the torque for low RPM due to sensor sensitivity. Nevertheless, it was possi...
The mechanical power for an electric generator is usually obtained from a rotating shaft and is equal to the shaft torque multiplied by the rotational, or angular, velocity. The mechanical power may come from a number of sources: hydraulic turbines at dams or waterfalls; wind turbines; steam tu...
The effect of SVM switching on torque ripple has been analyzed using "flux ripple vectors." This approach is used to develop an insight of torque ripple and to estimate it for any operating angular velocity. We propose a method of compensation to maintain steady state control of torque ...
This subsection presents a kinematic control and the design of a computed-torque control for the mechanical structure subsystem of the DDWMR. The configuration of the DDWMR can be described by the five generalized coordinates 𝑞=[𝑥,𝑦,𝜑,𝜃𝑟,𝜃𝑙]𝑇, where (𝑥,𝑦) are ...
