What is the difference between normal stress and shear stress?

Isnt that just a mechanical wave?

Waves are displacement due to stress. Stress is a force that's distributed across a surface instead of a single concentrated point. The distinction between normal and shear stress just tells you which way the force is acting relative to the surface, with normal stresses acting perpendicularly to the surface and shear stresses acting parallel to the surface. You can describe stress in any direction relative to a surface as a combination of normal and shear components.

Either you’re retarded, the teacher is retarded or both.

Tell me the question and I’ll explain it to you.

Is all the info OP needs.

Shear, tension, compression, ductability, plasticity, deflection, whatever first year physics or engy science teaches in statics and such spend literally less than a page, maybe a few paragraphs that OP should be able to just read and understand.

Maybe if youre a benchwarmer in academia

Normal stress is your everyday stress. For example, the stress of having to juggle your studies and work life. Shear stress is the stress one encounters in the situation of having to shear a sheep. This stress was named because many Welshmen would opt to fuck sheep rather than shear it as the shearing process was too stressful.

normal stress is compressive or tensile. beams holding up a building=compressive, cables holding up bridges = tensile, bending a solid rod = both.

shear stress could be likened to torque; it exhibits properties of normal stress but the angles of force are at right angles to the resistance applied by the medium.
