## How do you find the involute of a circle?

Circle Involute: x = r (cos t + t sin t) , y = r (sin t – t cos t), where, r = radius of the circle, t = parameter of angle in radian.

**What is meant by involute of a circle?**

The involute of a circle is the path traced out by a point on a straight line that rolls around a circle. The pedal of the involute of a circle, with the centre as pedal point, is a Spiral of Archimedes. Of course the evolute of an involute of a circle is a circle.

**What is the polar equation of a circle of radius?**

What is the Polar Equation of a Circle? The polar equation of the circle with the center as the origin is, r = p, where p is the radius of the circle.

### What is the radius of curvature of a circle of radius r?

1r

and thus the curvature of a circle of radius r is 1r provided that the positive direction on the circle is anticlockwise; otherwise it is −1r ….curvature of a circle.

**What is the most important property of involute curves?**

One of the most important characteristics of an involute gear is that it will transmit a uniform angular motion to the second gear, regardless of the changes of the distance between the centers of the two base circles [3, 8].

**What is the standard equation of circle?**

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius.

#### What is equation of cycloid?

Cycloid, the curve generated by a point on the circumference of a circle that rolls along a straight line. If r is the radius of the circle and θ (theta) is the angular displacement of the circle, then the polar equations of the curve are x = r(θ – sin θ) and y = r(1 – cos θ).

**Is a cycloid a half circle?**

As a adjective cycloid is resembling a circle; cycloidal.

**How to calculate the involute of a circle?**

Circle Involute: x = r (cos t + t sin t) , y = r (sin t – t cos t), where, r = radius of the circle, t = parameter of angle in radian. Catenary Involute: x = t – tanh t, y = sech t, where t be the parameter.

## How is the involute of a curve referred to?

The evolute of an involute of a curve is referred to that original curve. In other words, the locus of the center of curvature of a curve is called evolute and the traced curve itself is known as the involute of its evolute. This is part of a special branch of geometry called differential Geometry of Curves.

**Which is the involute of a tricuspid curve?**

3) Involute of a Deltoid- It is a tricuspid curve with three cusps. It resembles greek letter delta. Circle Involute: x = r (cos t + t sin t) , y = r (sin t – t cos t), where, r = radius of the circle, t = parameter of angle in radian. Catenary Involute: x = t – tanh t, y = sech t, where t be the parameter.

**What is the involute of the catenary curve?**

Catenary Involute: x = t – tanh t, y = sech t, where t be the parameter. where, r = radius of rolling circle involved in formation of deltoid.
