How it is tensor? We read it is a vector.

Tensors are the physical quantities that have different magnitudes and different directions at a point.
E.G: Moment of inertia of a disc (along the diameter and perpendicular to the diameter).

When I took classical mechanics we were given definitions for an object's moment of inertia, which I understand to be a scalar quantity that describes that objects tendency to resist rotation about a fixed axis either about, or some distance from its center of mass.
I was recently reading about how an object's moment of inertia can also be described as a tensor quantity when the axis of rotation is not fixed, but arbitrary.

Tensor means a quantity having magnitude and more than one direction. M.I has no direction. So it is scalar.

Moment of inertia is neither a scalar, nor a vector.
Some physical quantities which are neither scalars nor vectors which is called as 'tensors'.
So, Moment of inertia, pressure, stress, density, dielectric current, density, etc. are tensors.

Tensor: Those physical quantity whose magnitude are different in different direction.
So, the moment of inertia is tensor.

Tensor means the bodies will produce sound i.e. if we beat them it will emit sound waves and tungsten is having highest tensor property. Only metals are applicable for tensor. I think the answer will be in scalar or vector.

Why the pressure is a tensor quantity?

When there is no direction , only magnitude , M.I. is considered as a scalar.
When there is one direction & magnitude , it is a vector.
And when there are different magnitudes in diff. directions, it is a tensor(having more than one direction)
Hope its clear now.
