Question

The size of a cam depends upon:

• A. Base circle
• B. Pitch circle
• C. Pitch curve
• D. Prime circle

Hint:

In cam design, the base circle is crucial because it sets the geometry for the cam profile. Ensure that it is correctly defined to achieve the desired motion.

Answer 1

The Correct Option is A

The size of a cam is determined by the base circle. The base circle is the smallest circle from which the cam profile is generated and plays a key role in defining the overall size and shape of the cam. The other options, such as the pitch circle and prime circle, are related to the cam but do not directly determine the size of the cam. The base circle defines the limits within which the cam profile is formed, making it the most important factor in determining the cam size.
