fluid dynamics - Pseudo Force Direction





A cork and a metal Bob are connected by a string as shown in the figure. In case the beaker is given an acceleration towards left, the cork moves towards ..?

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
