Who can explain the normal stress and the axial force?. Shear stress and shear force. Does it matter? And then there is... Is shear generated in order to propagate bending moments?
Stress is the force reflected by the internal force of the section distribution (or converted to) the force on the unit area, the normal stress is in the normal direction, and the shearing stress is perpendicular to the normal direction. The axial force is the axial force, the tension or pressure on the axis of the shaft is divided by the cross sectional area, that is, the normal stress, no shear stress
Shear is shear, shear stress or shear stress, not what relation between the two, don't you two of them up.
If the end of shaft or any point is perpendicular to the axis of the force (such as cantilever, one end fixed and the other end or middle weight suspended), is subjected to shear stress and bending stress, shear stress is a section of shear force per unit area.2. yes. The beam (generalized) that bears the moment must be accompanied by shear forces.
