Question 1: The connecting link is machined from 1020 steel as-rolled. Determine the maximum compressive load it could support assuming a factor of safety = 3.
Question 2: The figure shows a hydraulic cylinder having a clevis mount. Because of the bearing and seal and because of the stiffness of the cylinder itself, the piston end of the rod may be regarded as fixed. The outboard end of the rod may be either a free end or rounded and guided, depending upon the application. Of course, the column length is taken as the distance I when fully extended.
Consider a typical application with a hydraulic pressure of 3500 psi, a 3-in cylinder bore, as factor a of safety of 3, and a medium-carbon-steel-rod material having a yield strength of 70 kpsi. Use the recommended value for end-condition constant, based on one end fixed and the other end tinned and guided, to find a safe diameter d for piston-rod lengths of 96, 48, and 24 in.
