Yes, a liquid can resist shear stress up to a certain extent, which is determined by its viscosity. Viscosity is a measure of a liquid's resistance to flow and deformation; higher viscosity means greater resistance to shear stress. However, unlike solids, liquids do not have a definitive shape and will eventually flow when subjected to sufficient shear stress. Therefore, while they can resist shear stress temporarily, they cannot maintain that resistance indefinitely.

What is the ratio of average shear stress to maximum shear stress for a circular section?
the average shear stress is 3/4 the maximum shear stress for a circular section
What are shear stresses?
The forces are equal magnitude but opposite directions act tangent the surfaces of opposite ends of the object the shear stress as force "f" acting tangent to the surface,dived by the "area"{a} shear stress=f/a
Difference between shear stress and critically resolved shear stress?
Shear stress refers to the force per unit area acting parallel to a material's cross-section, causing deformation. Critically resolved shear stress, on the other hand, is the minimum shear stress needed to initiate slip in a crystalline material, depending on the orientation of the applied stress relative to the crystal lattice. Essentially, while shear stress is a general measure of applied forces, critically resolved shear stress specifically relates to the conditions under which a material will yield or deform.
What are the difference kinds stress?
Normal stress and shear stress
Who discovered the shear stress and strain?
Robert Hooke in 1660 discovered the stress strain relation known as Hooke's law. The shear tress relation ( stress = rigidity modulus x shear strain) is a logical extension of Hooke's law,
Why fluids do not sustain shear stress?
Fluids do not sustain shear stress because they undergo continuous deformation under applied shear forces. Unlike solids that have a defined shape and can resist shear stress, fluids flow and deform when subjected to shear, resulting in no sustained shear stress. This behavior is a fundamental property of fluids known as viscosity.
What are the traits of a liquid?
A fluid is a substance that continuously deforms under an applied shear stress.
What is the relationship between resolved shear stress and critical resolved shear stress in materials science?
In materials science, the relationship between resolved shear stress and critical resolved shear stress is that the critical resolved shear stress is the minimum amount of shear stress needed to cause dislocation movement in a material. Resolved shear stress is the component of an applied stress that acts in the direction of dislocation movement. When the resolved shear stress exceeds the critical resolved shear stress, dislocations can move and deformation occurs in the material.
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.
How do you calculate the shear modulus of a material?
The shear modulus of a material is calculated by dividing the shear stress by the shear strain. This can be represented by the equation: Shear Modulus Shear Stress / Shear Strain.
Why liquids take the shape of the container?
they take the shape of a container because the liquid particles stay together but they still move around.Liquid is a fluid & fluid can't resist shear stress. they will continuously deform or change its shape even a small amount of shear force act. that is why they acquire the shape of the body in which the poured to come into stable position.
What is the ratio of average shear stress to maximum shear stress for a circular section?
the average shear stress is 3/4 the maximum shear stress for a circular section
Define direct shear stress?
Shear force is a load (pounds, or newtons) in plane of the object which produces shear stress ( pounds per sq inch, or Pascals). Shear force is related to shear stress as STRESS = FORCE/AREA
What is the relationship between shear stress and shear rate in fluid mechanics?
In fluid mechanics, shear stress is the force per unit area applied parallel to the surface of a fluid, while shear rate is the rate at which adjacent layers of fluid move past each other. The relationship between shear stress and shear rate is described by Newton's law of viscosity, which states that shear stress is directly proportional to shear rate. This means that as the shear rate increases, the shear stress also increases proportionally.

Why shear stresses are maximum at neutral axis?
according to bending stress because shear stress at neutral is 0 that is why shear force is maximum
