    Is pressure a rank 2 tensor?

    thanks for your continue support.sir you mistook me when i say i agree that at point the pressure of a gas in a container is same in all direction.What i did want to know if pressure has nothing to do with direction then why do one of the pressure law states that at poin in a static fluid...

    Is pressure a rank 2 tensor?

    have you ever heared anybody saying, this mass or time at a point (which are scalars)has same value in all direction?.

    Is pressure a rank 2 tensor?

    I do agree that in container containing gas the pressure at any point is the same in all directions.But why is there a need to say this if pressure is a scalar quantity?

    Is pressure a rank 2 tensor?

    yes yes you are right! but i want two know how we get the matrix before we diagonalise it?since when i have to begin i have a force with direction and an area in known direction.now i only can make an area vector and thus left with two vectors-force, and area(with direction taken perpendicular...

    Is pressure a rank 2 tensor?

    so i thought when a force(whic has some direction) acts on a surface then the force per unit surfce(which is defined as pressure) should act in the same direction and thus must have a direction in the direction normal to the surface.and as such when looking at force and area individually the...

    Is pressure a rank 2 tensor?

    first of all thanks for your reply.I orignally posted this my query in physics area sir.But in time i feel a need to discuss this topic here as such there is some mathematics is involved in it.tensors are better studied in terms of matrices.I have studied scalars are tensors of rank zero because...

    Is pressure a rank 2 tensor?

    Hi,all I am really very serious about what actually is the nature of pressure as a physical quantity.Books says it has no direction i.e. it is scalar some says it is not.but thinking ourselves it seems pressure has direction in the direction of applied force.Now I want to understand the...
