Question 1
Why is an offset provided in a radial cam-translating follower mechanism?
Question 2
The cam moves with a 300rpm, and has a least radius of 5cm. If the cam lifts the follower through 3.75cm when the cam attends 90 degree rotation in SHM. Determine the max. velocity of the follower during descent.
Question 3
In a cam design, the rise motion is given by a simple harmonic motion (SHM) 
where h is total rise, θ is camshaft angle, β is the total angle of the rise interval. The jerk is given by
where h is total rise, θ is camshaft angle, β is the total angle of the rise interval. The jerk is given by Question 4
Consider the following statements regarding cams:
1. A cam in which the follower moves radially from the center of rotation of the cam is known as a disc cam.
2. A globoidal cam is a double-disc cam, the two discs being keyed together and are in constant touch with the two rollers of a follower.
3. A conjugate cam can have two types of surfaces, convex or concave.
4. In a spherical cam, the follower oscillates about an axis perpendicular to the axis of rotation of the cam.
Which of the above statements are correct?
Question 5
A cam is a mechanical member used to impart a desired motion to a follower by direct contact. Which one of the under-listed follower motion types will produce the least jerk to the system?
Question 6
In circular arc cam with a flat faced reciprocating follower, the contact between the follower and the nose of cam is only maintained if:
