A) using singularity functions, write a single equation for m(x) along the beam. hint: use the constant ‘w’ for 30 lb/in and ‘ l’ for 120 in.; it will make the algebra in the next couple of parts much easier.
b) find the reactions at a and b.
c) find the deflection of the beam at x=120 in. if it is an s-beam (s24x80 structural steel; e = 29 x 106 psi; i = 2100 in4).

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
