Cross product between vecter and tensor

Click For Summary
The discussion centers on defining the cross product between a vector and a rank two tensor. The user references a formula from Wikiversity, stating that the cross product can be expressed as (x × T)_{iβ} = ε_{ijk} x_j T_{kβ}. They also present a related expression for (T × x)_{iβ} = ε_{jkβ} T_{ij} x_k. The user questions the validity of the relationship between the transposed tensors, specifically whether -(T^T × x) equals (x × T)^T. The conversation highlights the mathematical intricacies involved in tensor operations and their properties.

Homework Statement



Just wanted to ask what's the definition of the cross product between a vector and a range two tensor


The Attempt at a Solution



(x \times \hat{T})_{i\beta}=\epsilon_{ijk} x_j T_{k\beta}

if those were true, then is the following correct ?

<br /> <br /> -(\hat{T}^{T} \times x) = (x \times \hat{T})^{T}<br /> <br />
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
