What does epitrochoid mean?
An epitrochoid is a type of curve generated by tracing the path of a point on one circle as it rolls around the outside of another circle. This curve has several practical applications in engineering and design, particularly in the development of gear systems and other mechanical components. The epitrochoid is related to other types of curves, such as the cycloid and the trochoid, and is used to achieve smooth rotation and motion in various machines. Understanding the properties of the epitrochoid is essential for engineers and mathematicians working in these fields.
nounA curve traced by a point on the circumference of one circle as it rolls around the outside of another circle.
- A curve traced by a point on the circumference of one circle as it rolls around the outside of another circle.
"The epitrochoid is a type of curve that has several practical applications in engineering and design."
"The gear system uses an epitrochoid curve to achieve smooth rotation."

Etymology of epitrochoid
The term epitrochoid originates from the Greek words 'epi' meaning 'upon' and 'trochoid' meaning 'wheel-shaped'. The epitrochoid is a type of roulette curve, which is a curve traced by a point on a circle as it rolls along a straight line or another circle.
Usage notes
The term epitrochoid is primarily used in mathematics and engineering to describe specific types of curves.
