For the position shown where ? = 53°, point A on the sliding collar has a constant velocity of v=1.25 m/s in the direction shown. At this instant BD is horizontal and DE is vertical.a) Find the velocity of point D and angular velocity of link DE by using instantaneous center of zero velocity. b) Find the angular acceleration of link BD and DE.

SUBJECT- MACHINE ELEMENTS

The following diagram shows a piston moving in a cylinder with rod AB. Point B is rotating clockwise with an angular velocity of w. cylinder piston A connecting rod crank bearing B ResearchGate The motion of B is given by the equation r = C cos(wt) + Dsin(wt) Were r is the horizontal +vertical distance of B from O, and C, D are constants. For C=D=42mm and w = 20 rad/s. (i) Write r in the form Rcos (wt ± ß) and state the amplitude and period of r. (ii) Sketch one complete cycle of r. (iii) Explore the differences between the derived form and drawn form
