A student is trying to balance a long beam on a fulcrum so that the beam does not rotate. If the beam has two masses on it that are 7.84 meters apart (a 5.3 kg mass on the left end and a 22.7kg mass at the opposite end), where should the student place the fulcrum so the system will be in static equilibrium? Assume the beam is massless. Please show your work.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
