Respuesta :
The only option that can attain a maximum in the principal plane is; A: Normal stress
The options are missing and they are;
a) Normal stress b) Shear stress c) Shear strain
- Now, in beams sections or when dealing with rectangular sections subject to bending stresses and strains, there is what we call a principal plane and this principal plane is defined as the plane at which maximum stress occurs at an angle of 45°.
- Now, the principal plane is also defined as the plane at which the normal stress attains maximum and minimum values while the shear stress here is zero.
In conclusion, the only one that can attain a maximum in a principal plane is normal stress.
