In a static fluid:

a. Only normal stresses can exist: This means that there are no shear stresses present in a static fluid. Shear stresses occur when different layers of a fluid slide past each other, but in a static fluid, there is no motion or deformation happening.

b. Viscosity is nil: Viscosity refers to the resistance of a fluid to flow. In a static fluid, there is no flow occurring, so the viscosity is considered to be zero. This means that the fluid does not offer any resistance to deformation or movement.

c. Fluid pressure is zero: In a static fluid, the pressure is equal in all directions. This means that the fluid pressure is the same at any point within the fluid and is considered to be zero. There is no variation in pressure within a static fluid.

d. Resistance to shear stress is small: As mentioned earlier, in a static fluid, there are no shear stresses present. This implies that the resistance to shear stress is small or negligible because there is no deformation or movement happening in the fluid.

e. Linear deformation is small: Linear deformation refers to the change in shape or size of an object in one direction. In a static fluid, there is no significant linear deformation occurring because there is no motion or deformation happening in the fluid. Any changes in shape or size would be minimal or negligible.
