A mass my sits on a table, with a coefficient of friction μ between it and the table. A string runs from it under a pulley and up to mass m2, which is moving upward because someone is pulling up on it with a force F, as seen in the figure (Figure 1). The tension in the string is T.

A mass m₁ sits on a table, with a coefficient of friction
between it and the table. A string runs from it under a
pulley and up to mass m2, which is moving upward
because someone is pulling up on it with a force F, as
seen in the figure (Figure 1). The tension in the string is
T.
