Graphical Displacement Diagrams 9-1. A cam is required for an automated transfer mech- anism. The cam follower must rise outward 1.0 in. with constant velocity in 3.0 s, dwell for 0.5 s, fall with constant velocity in 2.0 s, and then repeat the sequence. Determine the required speed of the cam and graphically plot a follower displacement diagram.

Re-work Problem 4 on Homework 2 using Lagrange's equations (see Figure 4 below). As indicated in the original problem statement, find the equations of motion and the constraint force (Hint: to find the constraint force, introduce an additional generalized coordinate and associated Lagrange multiplier).

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. Answers are given, I need a help for to know how to draw and solve such a question

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.

Evaluate the 3-DOF wrist as shown in Figure 2, use the conventional method to determine 1. Linear velocity and 2. Angular velocity NOTE: for JOINT 3 ( 03 ) only Connected to robot arm Pitch Roll Yaw Figure 2: Wrist assembly The known position and orientation of the end of the arm point is.

In relation to Cams, the prime circle is which of the following: Select one: Oa. The theoretical point of the follower O b. None of these options Oc. The smallest circle tangential to the pitch curve O d. The smallest circle tangential to the cam surface O e. The locus generated by the trace point us page

Figure out the 2D sketch of rocker using AutoCAD and mention all the dimensions. Colour the hatched lines which are inside the curve (red) 88 12R 2 holes 12 Dia 40 R 10RY 14R 80 100 34 R 89 120 15

All pertinent rigid dimensions are specified for the linkage shown. Note that the ground pivot for the input link is at the origin of the coordinate system. The input angle []in is currently 170° measured from the x axis as shown. The figure is not exactly to scale, but it is reasonably close for checking purposes. (a) Calculate the value of the angle []out as shown on the figure. Use the equations developed from the loop closure method. Note that you will need to incorporate a change of coordinate axes orientation to the axes defined for the loop closure equations. (b) Calculate the absolute location of point P with respect to the coordinate axes shown. 18 30° 9° 9 P 20 50° -170° X
