For the joint shown below, an SAE Grade 5 7/8-9 screw connects two plates. The joint stiffness constant (C) has already been calculated to be 0.2012. The pre-load (F;) in the screw is 34500 lb. If an external axial load (P) of 6300 lb is applied to the connection, what is the magnitude of the (compressive) load in the material (in units of kip)? P P red 29.4673 (with margin: 0.5893) wers
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. Determine the endurance limit for this application. Assume that the size modification factor kis 0.85 until a size for the section is known. The endurance limit is 278.4 MPa.

Problem 5 High-strength stainless steel is required for use in building structures and equipment (e.g. , cranes). It is produced by heat treating quench-hardened steel in a process called tempering that reduces brittleness and imparts toughness. In a production facility, alloy steel plates (k=50 W/(m K), c=460 J/(kg K) and p=7865 kg/m³) of thickness 3 cm have to be tempered in a convective oven by heating them to 550°C. If the plates are initially at 40°C and the air inside the heat treating oven is at 700°C with a convective heat transfer coefficient of 45 W/(m? K), determine how long the plate has to remain in the oven.
Find factor of safety if the Ultimate Stress of a ductile material is 250.94 MPa. If the material is subjected to a loading condition that generates the working stress of 151.27 MPa
