On the basis of a given load of pulley Fr4000N, Determine the load of the bearing rope BA. The load should be the basis for the design of the supporting ropes, pulleys and ropes to mount joints A and B. Basically I need the moments and I need the reactions in the supports, these are somehow lattices. I need FA and FB and FC, and what is FBA?

Air undergoes a poly tropic process in a piston-cylinder assembly from P1 = 1 atm, T1 = 70ºF to P2 = 3 atm. Employing the ideal gas model with constant specific heats at 80ºF, determine the work and heat transfer per unit mass, in Btu/lbm, if
Ten moles of ethylene (T_c=9.2 degrees C, P_c= 214.2kg/m^3) are to be compressed isothermally from their initial state (P = 21.7 bar,T = 25 ºC, and V = 1000 cm3/mol) to 100 cm3/mol. Estimate the work required to perform this operation on an ideal gas..
The refrigerating efficiency is defined as the ratio of the cycle coefficient of performance to the coefficient of performance of a Carnot refrigeration cycle operating between thermal reservoirs at the ambient temperature and the temperature of t..
Helium gas is contained in a rigid vessel of 0.5 m3 at 500 kPa. The gas is agitated violently by a stirrer that transfers 250 kJ of work to the gas. Assuming that the system undergoes an adiabatic process, determine the final pressure of the gas. Ass..
