A trochoid refers to any of the cycloid, the curtate cycloid and the prolate cycloid. |
|
The scales may be cycloid, ctenoid, or absent and the lateral line is absent. |
|
Viviani determined the tangent to the cycloid but he was not the first to succeed in this. |
|
The brachistochrone is a cycloid, but that cycloid is not the only curve satisfying the equation. |
|
His last work was on the cycloid, the curve traced by a point on the circumference of a rolling circle. |
|
Actinopterygians may have ganoid, cycloid, or ctenoid scales, or no scales at all in many groups. |
|
He defines evolutes and involutes of curves and, after giving some elementary properties, finds the evolutes of the cycloid and of the parabola. |
|
He used the involute of a circle in his first pendulum clock in an attempt to force the pendulum to swing in the path of a cycloid. |
|
Only the arc lengths of transcendental curves such as the cycloid and the logarithmic spiral had been calculated before this. |
|
The prolate cycloid is similar to the simple cycloid except that the curve has no cusps and does not intersect the line. |
|
He constructed the first pendulum clock with a device to ensure that the pendulum was isochronous by forcing the pendulum to swing in a cycloid arc. |
|
Wrasses characteristically have a protractile mouth, cycloid scales, and a single continuous dorsal fin lacking an obvious notch between the soft and spiny portions. |
|
The sizing of a cycloid toothing is facilitated if, during the optimization, the counter wheel is calculated from the first wheel. |
|
An inverted cycloid is the brachistochrone, that is the curve between two points in a vertical plane, along which a bead needs the shortest time to travel. |
|
Both the evolute and involute of a cycloid is an identical cycloid. |
|
Roberval also found the volume of the solid formed by rotating the cycloid about the straight line through its endpoints. |
|
The cycloid is defined by two circle arcs with tip and root diameter values. |
|
Use this program module to evaluate special gearing, such as cycloid gearing. |
|
The entire dial is made of carbon-fibre and includes a large dial opening to admire the intriguing cycloid curve of the train wheels. |
|
The cycloid has the property that a particle P sliding on a cycloid will exhibit simple harmonic motion and the period will be independent of the starting point. |
|
|
Strength and geometrical properties of cycloid gearing can be analyzed via calculation of the path of contact under load and the stress curve and kinematics that are displayed there. |
|
Because of the curved, cycloidal profile of the cycloid disc, it progressively engages with the rollers of the ring gear housing to produce a reverse rotation at reduced speed. |
|
True bony fish have ctenoid or cycloid scales. |
|
Grammicolepidids have dorsoventrally elongate linear scales rather than the cycloid or ctenoid scales of other zeiform families. |
|
Results on the cycloid were discovered and rediscovered over the next two decades by Fermat, Descartes, and Blaise Pascal in France, Evangelista Torricelli in Italy, and John Wallis and Christopher Wren in England. |
|
Then the observer sees the electron moving on a curve which is a cycloid or trochoid, see Fig. |
|
An inverted cycloid with its base horizontal is a tautochrone. |
|
The scales are small, rudimentary, cycloid, relatively well embedded below the epidermis and therefore often difficult to see without magnification. |
