I have a bottle of gas, the bottle can expand and contract. Initially the gas is at 1 kpa of pressure and a volume of 1 Liter, at a temperature of 290 K. Then the Temperature went to 390 K and the volume of 1.1 Liter. What is the New Pressure?

The 0.5-kg flyballs of a centrifugal governor revolve at a constant speed v in the horizontal circle of 160-mm radius shown. neglecting the mass of links ab, bc, ad, and de, and requiring that the links support only tensile forces, determine the range of the allowable values of v so that the magnitudes of the forces in the links do not exceed 75 n.
