I need detail answer do not copy A cam is required for an automated transfer mechanism. The cam follower must rise upward 10 mm with constant velocity in 3.0 sec, dwell for 2 sec, fall with constant velocity in 4 sec, dwell for 1 sec, and then repeat the sequence .   a) Determine the required speed of the cam.   b) Draw the displacement diagram along with velocity curve.   c) The base circle diameter of the cam is 50 mm. Plot the cam profile when a knife-edge follower is incorporated.

3. Equally spaced parts, with the distance between the parts being 10 inches, are coming on a conveyor belt. A machine tool has to operate on the part for 0.5 second as the part is moving on the conveyor. The speed of the conveyor belt is 10 in/second. The tool will be attached to the follower of a cam mechanism that you will design. In other words, the motion of the tool is controlled by your cam. Design the svaj curves for the follower using polynomials. (Hint: When the tool is operating its velocity should be same as the part velocity.) Please explain all steps of your solution procedure clearly. You are not allowed to use any software to do this. [20 points]

question 14

You are given a task to design a cam. The cam are used for feed mechanism in automatic lathe machine. The motion of the cam follower that you need to design are given as follows: (b) 1. Move up 50 mm in 1 second using the harmonic motion 2. Dwell for 0.5 s 3. Move down 50 mm in 1 second using the harmonic motion 4. Dwell for 1 second The motions of the cam follower then will repeat the same sequences. (i) Calculate total time taken for the cam to complete a full circle motion. (ii) Calculate the rotational speed of the cam. (iii) Determine the cam rotation angle for each of the follower motion interval. (iv) Construct the follower displacement diagram for this cam

P A cam drive is used for a mechanism that moves a tool in an automated screw machining process. The cam follower must rise outward 24 mm with harmonic motion in 0.2 s, dwell for 0.3 s, fall 10 mm with harmonic motion in 0.3 s, dwell for 0.2 s, fall 14 mm with harmonic motion in 0.2 s, and then repeat the se- quence. Determine the required speed of the cam and graphically plot a follower displacement diagram.

The image below depicts one section of a cam shaft which opens a valve to release the pressure in the combustion chamber. In order to synchronize the position of the piston and the release of the valve, there is a sensor that measures the position of the camshaft. The sensor can determine when point a is 0.672 in. to the right of the center of the camshaft and 0.672 in. above the center of the camshaft. In a four stroke engine the crank shaft, which is connected to the pistons, turns twice for every turn of the camshaft. At cruising speed the crank shaft turns at 3,000 rotations per minute (rpm) which means that the camshaft turns at 1,500 rpm or 25 revolutions per second (rps). After 0.825 seconds, where would point a be in relation to the center of the camshaft?* Answer options are: (-0.589,0),(0.116, -0.316), (0,-0.95),(0.86,-0.315),(0.431,0), none of these are correct. Please be sure to show your steps.

Hello, I hope you can help me.  I'm trying to create a device that has a spinning axle and I need to change the rotational force to be perpendicular to the axle. I know there are gears that can fit together have teeth, like the attached picture.  I know there are other types of mechanisms, and some are more creative.  But I also need for the solution to be low friction. What are 2 low friction methods of changing the directional rotation of a power axle 90 degrees? The entire creation is small, probably 12" x 12" Thanks for your help.

Learning Goal: To understand how to use the relative position and velocity equations to find the linear and angular velocity of members in an assembly. A piston is driven by a crankshaft as shown. The crank arm (member AB) has a length of r₁=0.55 in and the connecting rod (member BC) has a length of r2 = 4.25 in. The crankshaft rotates in the counterclockwise or positive direction.
