Velocity ratio: The ratio of the number of revolutions of the driving (or input) gear to the number of revolutions of the driven (or output) gear, in a unit of time. Pitch point: The point of tangency of the pitch circles of a pair of mating gears. What is the gear ratio? A gear...
In a constant velocity ratio universal joint wherein a spider 7 has arms 8 pivoted at 10 to a driving fork 3 and arms 9 pivoted at 11 to a ring 12 which is pivoted to a driven fork 13, the axis of the pivot 11 is maintained equally inclined to the fork axes by bevel gears 18,...
If the ratio of the tube diameter to the duct diameter is smaller than 0.02, stem blockage can be neglected. Otherwise a correction has to be applied. The blocking effect does not apply to the Pitot-static tube alone. Any sensor/instrument immersed into a duct has a similar effect; the ...
In applying the above equation, when the ratio p2/p1approximately equals 0.53, under normal temperature conditions at sea level, the escape velocity v2will be equal to the velocity of sound. Increasing the pressure p1will not increase the velocity of escaping air beyond this limiting velocity unle...
The Velocity ratio of a simple screw jack formula is defined as the ratio of two times π multiplied to length of lever arm to the pitch of the screw and is
According to Formula (14), the measurement accuracy of the sensor for the flow rate is: 𝑆=Δ𝑓Δ𝑉=𝑁𝑆12𝜋𝑅1𝑆2.S=ΔfΔV=NS12πR1S2. (17) It can be seen from Equation (17) that the measurement accuracy of the sensor depends on the ratio of the cross-sectional ...
The Young’s modulus, CTE, and density of the FGM circular disks were assumed to vary exponentially only in the radial direction due to symmetry with respect to the axis of the disk for a constant Poisson’s ratio. Hooke’s law was applied, considering the contact forces, to obtain a ...
