Theory of Machine Angle of dwell of cam is defined as the angle Of rotation of the cam for 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 the 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 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 the highest position Moved by the cam from the instant the follower begins to rise, till it reaches its highest position ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A Hartnell governor has its controlling force (Fc) given by Fc = ar + b, where r is the radius of rotation and a and b are constants. The governor becomes isochronous when a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 a is +ve and b is also +ve a is +ve and b is -ve a = 0 and b is +ve a is +ve and b = 0 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if The sum of the two masses is equal to the total mass of body The center of gravity of the two masses coincides with that of the body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body All of these The sum of the two masses is equal to the total mass of body The center of gravity of the two masses coincides with that of the body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body All of these ANSWER DOWNLOAD EXAMIANS APP
