The force generated by a spring is given by F= kx where k is the spring constant, and x is the deflection of the spring. The spring shown in the figure has a spring constant of 9.5 kN/cm. The pressures are P-5000 kPa, P₂=10000 kPa, and P3= 1000 kPa. If the piston diameters are D-8 cm and D2-3 cm, how far will the spring be deflected?

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
