A sliding block C moves along a horizontal line Q2C. A rotation arm Q2B is 4 ft 3 in long and rotates around a center Q2. The connecting rod BC is 8 ft long. This rod is extended to D, making BCD 11 ft 9 in long. Make a drawing of this linkage and trace the path of D while the arm makes 1 complete revolution CCW. Locate points for each 15 deg movement of the arm Q2B, beginning with Q2B coinciding with Q2C. Scale: 1 in = 1 ft

Consider the Four-Degree-of-Freedom robot shown in figure Q1, and usethe following hints in your answer:Hint 1- Use frames {OO}, {O1} and {O4} as indicated in figure Q1.Hint 2- A joint can undergo a twist and a rotation at the same time

1. Figure 4.11 shows a kinematic diagram of a mechanism that is driven by moving link Graphically reposition the links of the mechanism as link 2 is displaced 30° counterclockwise. Determine the resulting angular displacement of link 4 and the linear displacement of point. B 3″ AD 4.9" 90° 0 5.3" 3.3" 10.1" D 3.2"

A general fourbar linkage configuration and its notation are shown in Figure below. The link lengths, coupler point location, and the values of 02 and w2 for the same fourbar linkages as used for position analysis in Chapter 4 are redefined in Table below. For the row c, draw the linkage to scale and Using an analytical method calculate w3 and w4 and find the velocity of point P. find the velocities of the pin joints A and.
