What is the difference between Bending and Direct Stress?
-> when a structural body gets deviated from its original position or from its centroidal axis due to externally applied load,then it is termed as BENDING->DIRECT STRESS is the stress which act normal to the plane-> stress and bending are the two different things. stress produced by load per area & bending is the effect produced by load and stress.
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

What is compressive strength of m25?
The compressive stress allowed is 25N/mm2. However, the strength of a concrete element depends on the arrangement of loads. For compression, the element might buckle before it reaches its compressive stress.
What are the permissible tensile and bending stress values for M20 concrete?
20kn/mm2
Explain why the stress is considered as a tensor quantity?
If the surface area is very very small then stress is a Tensor quantity.... -MOGRE
Is stress is scalar quantity or vector quantity?
Stress is tensor quantity. The stress tensor has 9 components. Each of its components has a magnitude (a scalar) and two directions associated with it.

Why is stress a tensor quantity?
stress is having magnitude, direction and point of application of force
What is the significance of the divergence of the stress tensor in the context of fluid dynamics?
In fluid dynamics, the divergence of the stress tensor represents the rate at which stress is changing within a fluid. It is significant because it helps to understand how forces are distributed and how the fluid is flowing. By analyzing the divergence of the stress tensor, researchers can gain insights into the behavior of fluids and make predictions about their movement and properties.
What is the relationship between the stress-energy tensor and the scalar field in the context of general relativity?
In the context of general relativity, the stress-energy tensor describes the distribution of energy and momentum in spacetime. The scalar field, on the other hand, is a mathematical concept that represents a scalar quantity at every point in spacetime. The relationship between the stress-energy tensor and the scalar field lies in how the scalar field can contribute to the stress-energy tensor, influencing the curvature of spacetime and the gravitational field in general relativity.
What is the significance of the Maxwell stress energy tensor in the field of electromagnetism?
The Maxwell stress energy tensor is important in electromagnetism because it describes how electromagnetic fields carry energy and momentum. It helps us understand how electromagnetic waves interact with matter and how energy is transferred in electromagnetic systems.
What is the significance of the first Piola stress tensor in the field of continuum mechanics?
The first Piola-Kirchhoff stress tensor is important in continuum mechanics because it allows for the description of stress in a material that is undergoing deformation. It helps in understanding the relationship between the forces acting on a material and its deformation, which is crucial for analyzing the behavior of materials under different conditions.
What is the significance of the Maxwell stress tensor in the context of electromagnetic fields?
The Maxwell stress tensor is important in understanding electromagnetic fields because it describes the distribution of electromagnetic forces and stresses within a given region of space. It helps in calculating the forces acting on charged particles and the energy stored in the electromagnetic field. This tensor is crucial for analyzing and predicting the behavior of electromagnetic fields in various applications, such as in electronics, communications, and optics.
What is a zero tensor?
A zero tensor is a tensor with all entries equal to zero.
What is the significance of the Einstein field equations in general relativity, particularly in relation to the stress-energy tensor and the metric tensor components f mu nu?
The Einstein field equations are a set of equations in general relativity that describe how matter and energy in the universe interact with the curvature of spacetime. The equations relate the curvature of spacetime (described by the metric tensor components) to the distribution of matter and energy (described by the stress-energy tensor). This relationship helps us understand how gravity works on a cosmic scale and has been crucial in predicting phenomena like black holes and gravitational waves.
Why pressure is a scalar quantity while stress is a vector?
For specifying pressure u need only magnitude, but for specifying stress u need magnitude,direction and plane Remember stress is not a vector but it is 2nd order tensor..........
