Draw an arc of radius 100mm construct an epicyloid for a circle of 15mm radius along the Arc?

To construct an epicycloid for a circle of 15mm radius along an arc of radius 100mm, follow these steps:

1. Draw the arc of radius 100mm.

2. Draw a circle with a radius of 15mm inside the arc, making sure it is tangent to the arc.

3. Choose a point on the circle and mark it as the starting point for the epicycloid.

4. Draw a line from the starting point to the center of the circle.

5. Using a compass, mark off the distance of the radius of the circle (15mm) along the arc from the starting point.

6. Draw a line from this new point on the arc to the center of the circle.

7. Repeat this process at regular intervals around the circle to create the epicycloid.

8. Connect the points on the arc to form the epicycloid curve.

Your completed epicycloid should now be constructed along the arc of radius 100mm for a circle of 15mm radius.
