Equilibrium:
แปลว่า(english) An object is in equilibrium if the resultant of the system of forces acting on it has zero magnitude. See static equilibrium and dynamic equilibrium.
Normal stress:
แปลว่า(english) Stress acting perpendicular to an imaginary plane cutting through an object. Normal stress has two senses: compression and tension. Normal stress is often simply called stress.
Shear:
แปลว่า(english) An system of internal forces whose resultant is a force acting perpendicular to the longitudinal axis of a structural member or assembly: sometimes called shear force.
Stress:
แปลว่า(english) The intensity of internal force acting at a point in an object. Stress is measured in units of force per area. See shear stress and normal stress.
goofy
Pressure:
แปลว่า(english) Pressure is a similar idea to stress, the force intensity at a point, except that pressure means something acting on the surface of an object rather than within the material of the object. When discussing the pressure within a fluid, the meaning is equivalent to stress.
