For a permanent bolted assembly with 12 bolts, the stiffness of each bolt is kb = 3 bf/in and the stiffness of the members is km = 10 bf/in per bolt. An external load of 60 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 5/8 in-13 UNC grade 7 bolts. (a) (2 points) Determine the yielding factor of safety. (b) (2 points) Determine the factor of safety based on joint separation. (c) (2 points) Determine the load factor for overload.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
