A steel loop ABCD of length 5ft and of 3/8" diameter is placed as shown around a 1" diameter aluminum rod AC. Cables BE and DF each 1/2" diameter are used to apply the load Q. Knowing that the ultimate strength of the steel used for the loop and the cables is 70ksi and that the ultimate strength of the aluminum used for the rod is 38ksi. Determine the largest load Q that can be applied if an overall factor of safety of 3 is desired.

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
