Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

6. There is air in the cylinder with the piston. The cross-sectional area of the piston is 5cm, the initial volume is 30cm, the pressure is 1 bar, and the temperature is 20℃. As shown in the picture next, the spring constant of the connected spring is ks=100 N/cm, and it is not deformed initially. By applying heat, the cylinder expands and the pressure in the cylinder becomes 4 bar. Answer the following questions. (hint: The relationship between P and V is straight) (1) Find the final volume (expressed in cm^3). (2) Find the expansion work during this process. (3) Find the amount of heat transfer during this process. Show this process on the P-v diagram
While the piston is pinned, a cylinder with a volume of 0.05 m3 contains 200 kPa pressure and 300 K air temperature. Since the pressure is 0.4 MPa as a result of the heat transfer from the environment, the pin breaks and when the system becomes thermodynamically equilibrium, its volume becomes 0.1 m3. The area of the piston is 0.05 m2, the masses of the piston and above are 150 kg and the atmospheric pressure is 102 kPa. a) Find the temperature when the pin breaks.b) Calculate the pressure and temperature after the pin breaks and reaches the equilibrium position.
