Hydraulics & Fluid Mechanics Fluid is a substance that has the same shear stress.at a point regardless of its motion cannot remain at rest under action of any shear force always expands until it fills any container cannot be subjected to shear forces has the same shear stress.at a point regardless of its motion cannot remain at rest under action of any shear force always expands until it fills any container cannot be subjected to shear forces ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics The normal stress is same in all directions at a point in a fluid irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity only when the fluid is frictionless When there is no motion of one fluid layer relative to an adjacent layer irrespective of the motion of one fluid layer relative to an adjacent layer only when the fluid is incompressible and has zero viscosity only when the fluid is frictionless When there is no motion of one fluid layer relative to an adjacent layer ANSWER DOWNLOAD EXAMIANS APP
Hydraulics & Fluid Mechanics A bucket of water is hanging from a spring balance. An iron piece is suspended into water without touching sides of bucket from another support. The spring balance reading will increase/decrease depending on depth of immersion increase remain same decrease increase/decrease depending on depth of immersion increase remain same decrease ANSWER DOWNLOAD EXAMIANS APP
