Compression members (4 points): The hydraulic cylinder shown below has a bore of 80 mm and is to operate at a pressure of 5.6MPa. With the clevis mount shown, the piston rod should be sized as a column with both ends rounded for any plane of buckling. The rod should be made of hot-rolled AlSI 1030steel. Assume a Young's Modulus of 207GPa. a. Apply a design factor of 3 and select the preferred size if the column length is 1.5m. (2 points) What is the actual factor of safety for the design? (2 points) b. [Useful tables are included at end of document] -80 mm
