A flat-faced follower is driven using a circular eccentric cam rotating at a constant angular velocity ω. At time t = 0, the vertical position of the follower is y(0) = 0, and the system is in the configuration shown below. The vertical position of the follower face, y(t) is given by
- e sin ωt
- e(1 + cos 2ωt)
- e(1 − cos ωt)
- e sin 2ωt
Correct answer: e(1 − cos ωt)
Solution
The correct option, e(1 − cos ωt), describes the vertical position of the follower as it moves in response to the circular motion of the eccentric cam. This equation captures the oscillatory motion of the follower, starting from the lowest point when t = 0, and reflects the relationship between the angular position of the cam and the follower's vertical displacement.
