In a cam design, the rise motion is given by a Simple Harmonic Motion (SHM) s = h 
1 - cos πθ 
2 β
where h is total rise, θ is camshaft angle, β is the total angle of the rise interval. The jerk is given by
-
-
h 1 - cos πθ 2 β
-
π h sin πθ β 2 β
-
π² h cos πθ β² 2 β
-
- π³ h sin πθ β³ 2 β
-
Correct Option: D
| The jerk is given by | |
| dt3 |
| If s = | | 1 - cos | | |||
| 2 | β |
| ∴ | = - | sin | | | |||||
| dt3 | β³ | 2 | β |
