I been reading some material that lead me to understand that it takes an inner product of a dyad and a vector to obtain another vector at an angle to the initial one... cross product among two vectors would be an option only if we are willing to settle to a right angle.(adsbygoogle = window.adsbygoogle || []).push({});

After few days i countered a situation where i see an inner product of a vector and a dyad resulting in a vector of different magnitude but same direction as the earlier one. i mean to say

[ A*v = η.v ]

A= a random dyad

v= a vector

η= a scalar.

now the question is, what is the condition for such an interaction ?? what should be the property of such a tensor ?!
