Theory of Machine Angle of ascent of cam is defined as the angle Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Of rotation of the cam for a definite displacement of the follower During which the follower returns to its initial position Through which the cam rotates during the period in which the follower remains in highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Of rotation of the cam for a definite displacement of the follower During which the follower returns to its initial position Through which the cam rotates during the period in which the follower remains in highest position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The fundamental equation for correct steering is (where φ and α = Angle through which the axis of the outer wheel and inner wheel turns respectively, c = Distance between the pivots of the front axles, and d = Wheel base) cotφ - cotα = c/b tanφ + cotα = b/c cosφ - sinα = c/b sinφ + sinα = b/c cotφ - cotα = c/b tanφ + cotα = b/c cosφ - sinα = c/b sinφ + sinα = b/c ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Which is the false statement about the properties of instantaneous center? The two rigid links which have no linear velocity relative to each other at this center have the same linear velocity to the third rigid link At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered The two rigid links have no linear velocities relative to each other at the instantaneous center The double center can be denoted either by O2 or O12, but proper selection should be made The two rigid links which have no linear velocity relative to each other at this center have the same linear velocity to the third rigid link At the instantaneous center of rotation, one rigid link rotates instantaneously relative to another for the configuration of mechanism considered The two rigid links have no linear velocities relative to each other at the instantaneous center The double center can be denoted either by O2 or O12, but proper selection should be made ANSWER DOWNLOAD EXAMIANS APP
