Required information A solid square rod is cantilevered at one end. The rod is 0.6 m long and supports a completely reversing transverse load at the other end of ±1.7 kN. The material is AISI 1080 hot-rolled steel. If the rod must support this load for 5 x 104 cycles with a design factor of 1.5, what dimension should the square cross section have? Neglect any stress concentrations at the support end. What will the strength of the metal be at 5 x 104 cycles? The strength of the metal at 5 x 104 will be MPa.
The spring of the check valve seen in the figure is mounted with a pre-stress of 12 mm and the diameter of the Spring Wire is 2.7 mm, the number of winding is 13, the slip module is 80800 N/mm?, the average diameter of the winding circle is 23 mm. If these conditions are taken into account, check the spring strength by finding out how much pressure the check valve will open at. Publication safe shear stress value is 185 N/mm? and 1 bar = 0.1 N / mm? will be taken. Ø10
