Q1. For the mechanism shown in figure, at this particular instant the vertical shaft is rotating along z-axis with an angular velocity (@ = 1 rad/sec) and angular acceleration (a = 2 rad/sec²). Note: When force F is applied on sleeve “J", it can slide up and down on vertical shaft (while sleeve “I " is fixed) and 0 can vary between 0° to 90° Select five right answers. 0.3 m 0.3 m a. All links (GH, EF, AB and CD) will have same angular velocity 0.3 m 0.3 m b. All links (GH, EF, AB and CD) will have different angular velocity c. Tangential Acceleration (a,) of link AB will not be zero d. Tangential Acceleration (a:) of link CD will be zero e. Angular Acceleration (a) of link AB will not be zero f. Angular Acceleration (a) of link CD will be zero g. All points on link CD will have same linear velocity, when 0 = 0° 0.1 m 0.i m h.
