[1]. The figure below illustrates part of a hydraulic crane. We are interested in the design (i.e., diameter) of the rod of its hydraulic cylinder. The length L of the rod is 1270 mm. The maximum applied cylinder pressure is 25 MPa. The hydraulic cylinder bore diameter is 75 mm. A medium carbon steel rod having a yield strength of 490 MPa is used. Determine the diameter of the rod for a factor of safety of 4. Assume a Young's modulus of 207 GPa for steel rod. Assume a pinned-fixed end condition for the rod (C=2). (2 marks) L=1270 mm [2]. Compute the maximum stress and deflection that can be expected in the steel machine member of rectangular cross-section carrying an eccentric load as shown in the figure below. The load P is 1000 lbf. If a design (or safety) factor of 3 is desired, specify the yield strength of the steel to be used for the machine member. Assume Young's modulus value of 30 MPsi for the steel member. The safety factor is to be applied to the load. (2 marks) A A -72 in- 0.50 in P -1.60 in- 40.80 in 0.80 in Section A - A
