DO YOU KNOW? 1. Describe the method to find the velocity of a point on a link whose direction (or path) is known and the velocity of some other point on the same link in magnitude and direction is given. 2. Explain how the velocities of a slider and the connecting rod are obtained in a slider crank mechanism. 3. Define rubbing velocity at a pin joint. What will be the rubbing velocity at pin joint when the two links move in the same and opposite directions? 4. What is the difference between ideal mechanical advantage and actual mechanical advantage?

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]

Sketch the appropriate diagrams and label them. Explain your reasoning.!

Acceleration analysis of Scotch Yoke Mechanism Please can you show the working of 'Now fixing the angular velocity at 1.5 rad/s and crank length of 40 mm. by Changing the  crank angle'. from the follow up question.(how did you get the value) and can you show me the working and answers of "First fix the crank length 40 mm with crank angle 240°. By changing the angular velocity " (follow up question). and also show me the working of "changing the crank length :"(follow up question)

Identify which variables are the outputs or how they relate to the outputs. Plug in all possible numbers. Assuming link 2 rotates at a constant rate of 80 rpm CW, determine the velocity of link 6 when link 2 makes a 10-degree angle with the ground (measured as a right hand horizontal)

When the driver is moving clockwise, find the magnitude of the velocity of point C in terms ofvelocity A using any of the methods

Mechanism design

find average piston velocity in each direction ( between limiting positions) for an off-set slider crank mechanism. The crank length is 2". The connecting rod length is 4 " and the offset is 1". the crank speed is 3000 rpm CW.
