The sequence in Figure P2.2 represents a ball rolling into a walland bouncing off of it. The ball is 10 mm in diameter. Make agraph showing the distance from the leading edge of the ballto the closest part of the wall (using the wall as the origin) asit changes from frame to frame.
Pls help me with my plates
Block 4 slides in the slot in the fixed piece 1. Axis Q2 of crank 2 is fixed on 1. Q2A = 1.5 inches, and AB = 4.5 inches. Draw the mechanism, assuming dimensions for 1, if desired or use center lines only. Draw the four-bar linkage for this mechanism, properly rotate the linkage Q2ABQ4∞, name each link, and show the finite infinite cranks.
Draw the kinematic diagram of the following mechanism
