Theory of Machine The advantage of the piston valve over the slide valve is that in the former case Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing Wear is less Both wear and power absorbed are low Power absorbed is less The pressure developed being high provides tight sealing 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 mm 3.0 mm 2.22 mm 2.50 mm 2 mm 3.0 mm 2.22 mm 2.50 mm ANSWER DOWNLOAD EXAMIANS APP
