    Piston problem -- Method to increase the force against a spring

    I assume that when the system is 100 degrees F is not applying any bone strength the system is in equilibrium. I was able to determine that the saturation pressure of R-134a table are as follows: 100 degrees F the saturation pressure is 138.93 psia. 70 degrees F the saturation pressure is...

    Piston problem -- Method to increase the force against a spring

    Hi people, I need help to this problemSomeone has suggested that the device shown in the figure below be used to improve the maximum force F against the spring, which has a spring constant of k. This is accomplished by changing the temperature of the liquid-vapor mixture in the container. You...
