  2. In a cam-follower, the follower rises by h as the cam rotates by (radians) at constant angular velocity (radians/s). The follower is uniformly accelerating during the first half of the rise period and it is uniformly decelerating in the latter half of the rise period Assuming that the magnitudes of the acceleration and deceleration are same, the maximum velocity of the follower is

  6. A thin-walled cylindrical can with rigid end caps has a mean radius R=100 mm and a wall thickness of t-5 mm. The can is pressurized and an additional tensile stress of 50MPa is imposed along the axial direction as shown in the figure. Assume that the state of stress in the wall is uniform along its length. If the magnitudes of axial and circumferential components of stress in the can are equal, the pressure (in MPa) inside the can is decimal places) _(correct to two end cap end cap Pressurized can 50MPa 50MPa
