- Following data relates to cam and follower mechanism, find out speed of cam in rpm and max. Usable speed of cam without jump if a cam is an eccentric cam with eccentricity 3 cm driving a follower of mass 1.5 Kg. The spring holding the cam has stiffness of 20 N/mm and initial compression 3.15 cm. The jump is observed at 75° of cam rotation from the lowest position of cam. 0arrow_forward3. A double-dwell cam moves a follower from 0 to 2.5" in 60°, dwells for 120°, falls 2.5" in 30°, and dwells for the remainder. The total cycle takes 4 seconds. The sine acceleration is used for both rise and fall intervals. Calculate the constant angular velocity of the cam. Determine the maximum values of the follower's velocity and acceleration in both rise and fall intervalsarrow_forwardPlease answer the question in 5mins I will rate your answer. Cam mechanisms are used in many machines. For example, cams open and close the valves in your car engine to admit gasoline vapor to each cylinder and to allow the escape of exhaust. The principle is illustrated in the figure below, showing a follower rod (also called a pushrod) of mass m resting on a wedge of mass M. The sliding wedge duplicates the function of a rotating eccentric disk on a camshaft in your car. Assume that there is no friction between the wedge and the base, between the pushrod and the wedge, or between the rod and the guide through which it slides. When the wedge is pushed to the left by the force F, the rod moves upward and does something such as opening a valve. By varying the shape of the wedge, the motion of the follower rod could be made quite complex, but assume that the wedge makes a constant angle of ? = 19.0°. Suppose you want the wedge and the rod to start from rest and move with constant…arrow_forward
- 1. A cam must rise in 3 seconds at constant velocity of 0.25 in/sec in the first segment. Then the follower must return to the zero position in 5 seconds with a full return cycloidal motion and then dwell for 3 seconds in segment 3. The final segment will be a full rise cycloidal motion. The total cycle time is 12 seconds, and the maximum height is in the first segment. Full return cycloidal motion 1 y = L + sin 2π Full rise cycloidal motion y = L sin Determine the following: The cam angular velocity. b. The cam rotation segment widths, B1 c.

The follower then return to its original position through an angle 0R and then dwell for the rest of the cam rotation of 110°. The displacement of the follower is to take place with constant speed motion during both the outward and return strokes. The least radius of the cam is 4 cm. If the cam rotates at 300 r.p.m., construct the displacement, velocity and acceleration diagrams. Also determine The displacement, velocity, acceleration and the pressure angle for the following angles (40°, 75°, 145°, 200°).arrow_forward

One cycle of the cam has the following motion requirements: Rise to 40 mm in 1.5 s, Dwell for 0.25 s, Fall for 20 mm in 1 s; Dwell for 0.25 s; Fall a further 20 mm in 1s and the cycle repeats after this.

This is the same speed at which the cable of the winch is pulled in.arrow_forwardA cam drives a flat reciprocating follower in the following manner. During the first 90° rotation of the cam, the follower moves outward through a distance of 30 mm with SHM. The follower dwells during next 90° cam rotation. During the next 90° cam rotation, the follower moves inward with SHM. The follower then dwells next 90° cam rotation.
