## Where the shear stress is maximum?

the neutral axis

The maximum shear stress occurs at the neutral axis and is zero at both the top and bottom surface of the beam. Shear flow has the units of force per unit distance.

### Does a plane of maximum shear stress contain?

When the shaft is subjected to pure torsion the normal stress in the plane of maximum shear will be zero. While for other cases the normal stress will exist in the plane of maximum shear stress.

**Is the maximum in plane shear stress the absolute maximum shear stress?**

On plane xy there will be one maximum value of shear stress and same for other two planes so we will get three values of maximum stress (inplane maximum shear). Out of these three inplane maximum shear stress the one who’s value will be maximum called absolute maximum shear stress.

**Can we have a situation where shear stresses are maximum and normal stresses are 0?**

It is interesting to note that the shear stress, τx′y′ will go to zero when the stress element is rotated θp. At the principal stress angle, θp, the shear stress will always be zero, as shown in the diagram. And the maximum shear stress will occur when the two principal normal stresses, σ1 and σ2, are equal.

## What is the maximum stress?

The maximum stress refers to the maximum tensile stress while the minimum stress refers to the minimum compressive stress. The stress range was taken as the absolute difference between the maximum and minimum stress.

### Why shear stress is maximum at Centre?

Under certain assumptions (laminar flow) a Poiseuille flow profile will appear in a channel. In that case, the flow velocity is maximum in the center, but the gradient will be zero in the center. At the wall, the flow will be zero, but the gradient will have a maximum value, therefore maximum shear stress.

**What is Max absolute stress?**

What is the definition of Max Absolute? Answer: The membrane stresses and bending stresses can be combined to form the principal stresses, SMAX and SMIN, on the top and bottom surfaces of plate elements.

**What is the normal stress on plane where maximum shear stress is acting Mcq?**

The shear stress on the principal plane is zero. The planes of maximum and minimum normal stresses are at an angle of 90° to each other.

## Which plane carries maximum normal stress?

Detailed Solution. Maximum and minimum values of normal stresses occur on planes of zero shearing stress. The maximum and minimum normal stresses are called the principal stresses, and the planes on which they act are called the principal plane.
