The pressure angle of a cam is an important parameter in cam design, as it affects the force distribution between the cam and the follower, as well as the wear and tear on the components. Let’s evaluate each statement to determine which ones are correct:
Lift and type of the follower motion: The lift (or stroke) of the follower and the type of follower motion (such as uniform velocity, simple harmonic motion, or cycloidal motion) directly affect the cam profile and, consequently, the pressure angle. Therefore, this statement is correct.
Angle of ascent: The angle of ascent refers to the angle through which the cam rotates while the follower rises. This affects the velocity and acceleration of the follower and thus impacts the pressure angle. Therefore, this statement is also correct.
Offset between center line: If the follower is offset from the center line of the camshaft, it affects the geometry of the cam profile and the pressure angle. Hence, this statement is correct as well.
Since all three factors influence the pressure angle of a cam, the correct answer is: 1, 2, and 3

Factors affecting the pressure angle of a cam:
1. Lift and type of the follower motion:
The pressure angle of a cam is influenced by the lift of the follower as well as the type of motion the follower undergoes. The magnitude of lift and the nature of follower motion determine the contact angle between the cam and follower, which in turn affects the pressure angle.
2. Angle of ascent:
The angle of ascent refers to the angle at which the follower rises during the cam cycle. The steepness or shallowness of this angle can impact the pressure angle of the cam. A steeper angle of ascent may lead to a higher pressure angle, while a shallower angle may result in a lower pressure angle.
3. Offset between center line:
The offset between the center lines of the cam and follower also plays a role in determining the pressure angle. The distance between these center lines affects the contact point between the cam and follower, influencing the pressure angle.
Therefore, all three factors - lift and type of follower motion, angle of ascent, and offset between center lines - have a combined effect on the pressure angle of a cam. These factors need to be carefully considered and optimized during the design of cam mechanisms to achieve the desired performance characteristics.
