Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2.22 mm 2 mm 3.0 mm 2.50 mm 2.22 mm 2 mm 3.0 mm 2.50 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is said to be isochronous when the controlling force Increases as the radius of rotation decreases Decreases as the radius of rotation increases Remain constant for all radii of rotation Increases as the radius of rotation increases Increases as the radius of rotation decreases Decreases as the radius of rotation increases Remain constant for all radii of rotation Increases as the radius of rotation increases ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler.
