Theory of Machine The condition for correct steering of a Davis steering gear is (where α = Angle of inclination of the links to the vertical) cosα = c/b cotα = c/2b sinα = b/c tanα = c/2b cosα = c/b cotα = c/2b sinα = b/c tanα = c/2b ANSWER DOWNLOAD EXAMIANS APP
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 2.50 mm 2.22 mm 3.0 mm 2 mm 2.50 mm 2.22 mm 3.0 mm 2 mm ANSWER DOWNLOAD EXAMIANS APP
