physics

A force,
F = (2x + 5y) N,
is applied to an object at a point whose position vector with respect to the pivot point is
r = (2x + 4y + 5z) m.
Calculate the torque created by the force about that pivot point.

  1. Torque is the F x r vector cross product.

    Do your x, y and z represent unit vectors?

    It is conventiuonal to use i, j and k for unut vectors along x, y and z orthogonal axes.

    I am confused by your notation.
