It is very important to find the shear center for the beams or sections that are undergoing majority of the load under torsion or twisting then the material will not fail under torsion as at shear centre there will be no effect of torsion or twisting. It will fail only by bending or any other force.

∙ 13y agoThe shear center is a point on a material where shear force is applied without inducing torsion. This allows one to attach a horizontal beam that induces a shear force at a location that will keep the beam from bending.

What is the significance of shear stress and shear strain curve and what does it represent?
hi .. this Q I have asked you to answer it ..... how can I answer it if I have knowing the answer so why I aske you to answer me ...
What is the difference between shear center flexural center center of twist and elastic center?
The elastic center that point of a beam in the plane of the section lying midway between the flexural/shear center and the center of twist in that section. The flexural center and the shear center are the same thing. It is that point through which the loads must act if there is to be no twisting, or torsion. The shear center is always located on the axis of symmetry; therefore, if a member has two axes of symmetry, the shear centre will be the intersection of the two axes. Channels have a shear center that is not located on the member. The center of twist is the point about which the section rotates when subjected to torsion. If the object is homogeneous and symmetrical in both directions of the cross-section then they are all equivalent and are located at the beam centroid.
How do you determine shear center for any section?
the sum of all vertical forces is called shear force

What is difference center of shear and center of twist?
The shear center is the point on a beam cross section at which an applied shear force (lateral load or load parallel to the cross section) will produce bending but no twisting of the section. The center of twist is a point in a cross section that remains stationary when a twisting moment (torque) is applied on that cross section. The shear center and twist center are the same point only when the beam is rigidly supported.

Location of shear wall in a building?
in place of the center of mass and center of rigidity is the same
What is the practical application of shear center?
The way I understand it is that the shear center is the point of a cross-section, where loads can be applied without causing torsion over the longitudinal axis (normal to the cross-sectional plane).
Where will you find the maximum shear stress in a beam?
The maximum stress occurs where shear load is maximum and maximum stress is at the center of the beam cross section if loaded in shear due to bending. It drops to zero at the top and bottom surfaces. The average stress is load divided by area ; maximum stress is dependent on shape of cross section and is 1.5 times load divided by area at the cross section center for rectangular cross section. For shear due to twist, max shear stress in the outer surface.
Why shaft diameters are not calculated using relation shear stress by radius equals g x theta by L and what is the significance of the radius so found?
If you know the allowable shear strength and the shaft is only in torsion, your equation is correct - the radius is the maximum you can have before failure, knowing the shear strength. Diameter is two times radius
Where in the in cross section minimum shear stress is developed in case of a circular shaft under torsion?
Under torsion only, the shear stress is minimum, in fact zero, at the center point ( where radius is zero)
Relationship between the shear stress and angle of shear?
Shear Stress divided by the Angle of Shear is equals to Shear Stress divided by Shear Strain which is also equals to a constant value known as the Shear Modulus. Shear Modulus is determined by the material of the object.
What is a homophone for shear?
A homophone for "shear" is "sheer".

The difference between a positive shear and a negative shear is the direction the image is distorted into
