You are interested in determining how different elements of the cytoskeleton of the cell act together to support loads. You decide to model the cytoskeleton using the principles of a truss (this model is also known as biotensegrity) under loading where the contractile microfilaments and cytoskeletal microtubules are modelled as two-force members. Where the cell attaches to the extracellular matrix, the cellular adhesion sites are modelled by a pin at A and a roller at E. Determine the minimum cross-sectional area required if the normal stress in each cytoskeletal "truss member" must not exceed 0.23 GPa in tension and 0.35GPa in compression given

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.
