The linkage Q₂BCDEQ4KF represents the mechanism of the Corliss non-releasing valve gear. Q₂B is a crank 3%8- inches long oscillating to the right of fixed center Q₂. Q₂C is another crank which is 3%-inches long and oscillates below Q₂. Q4 is a fixed center on a horizontal line through Q₂ and 6-inches to right of Q₂. EQ4K to right of Q4E. Q4E = 3%- inches and Q4K = 5-inches. CE is a connecting rod 3½-inches long. BD is a link 2 - inches long connecting B to link CE at D, 1-inch. from C. KF is a connecting link 8- inches long extending to right of K and is attached to a slide block at F which moves on a horizontal line parallel to and 3-inches below Q₂Q4. When F, moving to left, reaches a position such that K is to the left of Q4, and Q4K makes an angle of 15° to left of vertical, it has a velocity of 5 fps. 1.1 Draw and label the mechanism of the Corliss non-releasing valve gear. 1.2 Find the velocity K in feet per second 1.3 Find the velocity of E in feet per second 1.4 Find the velocity of C in feet per second 1.5 Find the velocity of D in feet per second 1.6 Draw the velocity Polygon by the semi graphical method 1.7 Determine and tabulate the instantaneous acceleration of K in feet per second per second 1.8 Determine and tabulate the instantaneous acceleration of E in feet per second per second 1.9 Determine and tabulate the instantaneous acceleration of D in feet per second per second 1.10 Determine and tabulate the instantaneous acceleration of C in feet per second per second 1.11 Determine and tabulate the instantaneous acceleration of B in feet per second per second 1.12 Draw the acceleration polygon by the semi graphical method. 1.13 Determine and tabulate the instantaneous angular velocity of link KF 1.14 Determine and tabulate the instantaneous angular velocity of link Q4K 1.15 Determine and tabulate the instantaneous angular velocity of link Q₂C 1.16 Determine and tabulate the instantaneous angular acceleration of link KF 1.17 Determine and tabulate the instantaneous angular acceleration of link Q4K 1.18 Determine and tabulate the instantaneous angular acceleration of link Q₂C Scales: Space, ½/2 in. = 1 in.; velocity, 1 in.-2.5 fps; acceleration to be chosen.
