tensor calculus - Why is stress a scalar quantity, even though ...

WitrynaSo pressure is the scalar part of the stress tensor, and it is the only part of the stress tensor that exists in fluids. @Ron; I agree that "pressure" as it's usually defined is a scalar. But the OP defined pressure in terms of the force on a small unit area (which has an orientation) and so is not generally a scalar. WitrynaFrom a modern physics viewpoint, time is not a vector nor a scalar, it is a coordinate. This is because time is relative depending on the observer, so it cannot be defined as a scalar or a vector. In Newtonian physics, however, time has a universal meaning and is usually thought of as a scalar. In physics, there are a number of different ...

However, since a directional derivative is the dot product of the gradient and a vector it has to be a scalar. But, in my textbook, I see the special case of the directional derivatives Fx(x, y, z) and Fy(x, y, z) being treated as vectors. I want a clarification for this.

Witryna11 wrz 2024 · The dot product is known as a scalar product and is invariant (independent of coordinate system). An example of a dot product in physics is mechanical work which is the dot product of force and distance: (14.5.7) W = F → ⋅ d →. The cross product is the product of two vectors and produce a vector. Witryna30 maj 2024 · The meaning of the statement that the stress tensor is not a vector refers uniquely to the fact that it is neither a direction nor a force.
