MECHANICS QUESTIONS AND
VERIFIED ANSWERS|100%
CORRECT|GRADE A+
a fluid deforms continuously when subjected to ________ - ANSWER shear stress
______ and ______ are hige for incompressible - ANSWER
what is rigid body approximation - ANSWER if the fluid is at rest or there is no relative motion between
particles then the shearing stress is not present
mention two things which can satisfy rigid body approximation - ANSWER the fluid is at rest or there is
no motion between relative particles
state pascal law (1) - ANSWER Pressure acts uniformly in all directions on a small volume (point) of a fluid
state pascal law for fluid confined in a solid boundary - ANSWER for a fluid confined in a solid boundary
the pressure acts perpendicularly to the surface (pressure formed by normal force)
dp/dz=-rho*g (what is the name of the formula) - ANSWER barometric equation (basic equation of fluid
statics)
basic equation is valid when_____ - ANSWER there is no shear stress on the vertical face of the cube
when can we say shear stress happen - ANSWER when there is different vertical velocity in each side
the basic equation applies when the fluid is not moving at all(true/false) - ANSWER true
the absolute pressure of a fluid is expressed relative to - ANSWER vaccum
