- Being a second rank tensor in four dimensions, the energy momentum tensor may be viewed as a 4 by 4 matrix.
- In three dimensions, angular velocity can be represented by a pseudovector because second rank tensors are dual to pseudovectors in three dimensions.
- Similarly, every second rank tensor ( such as the stress and the strain tensors ) has three independent invariant quantities associated with it.
- If you view the Riemann tensor as a second rank tensor acting on bivectors, the vanishing of invariants is analogous to the fact that a nonzero null vector has vanishing squared length.
- The algebraic classification of bivectors given above has an important application in relativistic physics : the electromagnetic field is represented by a skew-symmetric second rank tensor field ( the electromagnetic field tensor ) so we immediately obtain an algebraic classification of electromagnetic fields.
- Note that the gradient of a vector is a special case of the covariant derivative, the operation results in second rank tensors; except in Cartesian coordinates, it's important to understand that this isn't simply an element by element gradient.
- It's difficult to see second rank tensor in a sentence. 用second rank tensor造句挺難的
