A box of mass m sits on the smooth (frictionless) ground. It is subject to a force of magnitude T to the left being exerted by a horizontal rope. A box of mass m2 is on top of the first box; this second box is subject to a force of magnitude T up and to the right being exerted by another rope. The rope makes an angle 0 with the horizontal, and the coefficient of static friction between the two boxes is . This is shown in the diagram below. T m m2 ,
