Question

The point on the cam at which the pressure is maximum is known as:

• A. Pitch point
• B. Trace point
• C. Roller centre
• D. Cam centre

Hint:

The pitch point is the key location on a cam where the pressure is maximized due to direct contact with the follower.

Answer 1

The Correct Option is A

Step 1: Understanding the Cam Profile
The cam profile plays an essential role in converting the rotational motion into the required follower motion. The pressure at any point on the cam is influenced by the cam profile and the motion it imparts to the follower.
Step 2: Pitch Point Definition
The pitch point is the point on the cam where the follower is in direct contact with the cam profile, and it is at this point where the pressure between the cam and the follower is typically at its maximum. This point is critical because it corresponds to the point of maximum tangential force.
Step 3: Conclusion
Thus, the point on the cam where the pressure is maximum is called the pitch point.
