Question

[CLO-6] A cam is to give the following motion to a flat-faced radial follower: • To raise the follower through 30 mm with uniform acceleration and deceleration during 120$^{\circ}$ rotation of the cam (half acceleration and half deceleration) • Dwell for next 30$^{\circ}$ of the cam rotation • To lower the follower with SHM 6 during the next 90$^{\circ}$ rotation of the cam • Dwell for the rest of the cam rotation. The cam has a minimum radius of 30 mm and rotates counter-clockwise at a uniform speed of 800 rpm. Specify the length of the follower face (if the factor of safety is 4 mm). SHM - 6: $S = \frac{L}{2} \left( 1 + cos \frac{\pi\theta}{\beta} \right)$ A. 32.65 mm B. 62.65 mm C. 58.65 mm D. 34 mm

A cam is to give the following motion to a flat-faced radial follower:
• To raise the follower through 30 mm with uniform acceleration and deceleration during 120\(^{\circ}\) rotation of the cam (half acceleration and half deceleration)
• Dwell for next 30\(^{\circ}\) of the cam rotation
• To lower the follower with SHM 6 during the next 90\(^{\circ}\) rotation of the cam
• Dwell for the rest of the cam rotation.
The cam has a minimum radius of 30 mm and rotates counter-clockwise at a uniform speed of 800 rpm.
Specify the length of the follower face (if the factor of safety is 4 mm).

[CLO-6]
A cam is to give the following motion to a flat-faced radial follower:
• To raise the follower through 30 mm with uniform acceleration and deceleration during 120^∘ rotation of the cam (half acceleration and half deceleration)
• Dwell for next 30^∘ of the cam rotation
• To lower the follower with SHM 6 during the next 90^∘ rotation of the cam
• Dwell for the rest of the cam rotation.
The cam has a minimum radius of 30 mm and rotates counter-clockwise at a uniform speed of 800 rpm.
Specify the length of the follower face (if the factor of safety is 4 mm).
SHM - 6: S = (L)/(2)( 1 + cos (πθ)/(β))
A. 32.65 mm
B. 62.65 mm
C. 58.65 mm
D. 34 mm
