A double acting cylinder is used to move a load in reciprocating motion 10 cycles per minute with 70 N force in both directions along 70 cm distance as shown in the following figure. If the pneumatic system works at ordinary pressure (6 bar), answer the following questions: 70 cm 70 N 1. Select the suitable piston diameter from the graph (Check your answer by calculation) 2. Find the minimum allowable rod diameter that prevent buckling effect. 3. Check if the selected piston and rod diameters are sufficient to move the load. 4. Calculate the cylinder air consumption (Check your answer by using monograph).
