A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise-fall periods and rise and fall periods should be same. The maximum rise in follower is 45 mm. How much the follower will rise when the follower is 45 degrees from its initial position of a cam?

Correct Answer: 22.5
According to the given conditions there is only movement in follower up to 180 degrees of shaft rotation and between it at the middle the follower make maximum rise that is at 90 degrees. 90- 45 = 45 degrees. For 90 degrees it is 45 mm so for 45 degrees it will be 45/2 = 22.5 mm when the follower is 45 degrees from its initial position of the cam.

A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise -fall periods and rise and fall periods should be same. The maximum rise in follower is 30 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within first half of cam profile, the remaining is dwell period, and without any dwell period in between the rise-fall periods and rise and fall periods should be same. The maximum rise in follower is 35 mm. How much the follower will rise when the follower is 240 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within the second half of cam profile, the first half is dwell period, without any dwell period in between the rise and fall periods and rise and fall periods should be same. The maximum rise in follower is 45 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within the second half of cam profile, the first half is dwell period, without any dwell period in between the rise and fall periods and rise and fall periods should be same. The maximum rise in follower is 55 mm. How much the follower will rise when the follower is 240 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall throughout the cam, without any dwell period and rise and fall periods should be same. The maximum rise in follower is 50 mm. How much the follower will rise when the shaft is rotated to an angle of 120 degrees?

A cam should be designed only using uniform rise and fall throughout the cam without any dwell period and rise and fall periods should be same. The follower is making a rise of 40 mm when the shaft is rotated to an angle of 150 degrees. What is the maximum rise in a follower?

The angle of elevation of the top of a 36 m tall tower from the initial position of a person on the ground was 60 deg. She walked away in a manner that the foot of the tower, her initial position and the final position were all in the same straight line. The angle of elevation of the top of the tower from her final position was 30 deg. How much did she walk from her initial position?

A cam profile is drawn which gives a uniform rise and fall of 60 mm to a point during each revolution of cam. The follower will rise to a distance of ____ mm if the shaft is rotated to an angle of 180 degrees.

The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r1 = Minimum radius of the cam, r2 = Radius of the roller follower and $$\theta $$ = Angle turned by the cam from the beginning of the follower displacement)

A cam profile is drawn which gives a uniform rise and fall of 40 mm to a point during each revolution of cam. The follower will rise to a distance of 20 mm if the shaft is rotated to an angle of _____
