DATA FOR THE QUESTION IS :
Question #1 10 marks Draw a simple hydraulic Circuit which will operate a hydraulic cylinder of a machine. The load during forward stroke is 15 KN and that during return stroke is approximately 9.5 KN. The forward and return speeds are about 3.5 m/min and 5.5 m/min respectively. The total stroke of the cylinder is 400 mm. A provision is required to hold the cylinder anywhere in between the end positions. Select the different...
