A block rests on a rough table and is connected by a string that goes over a pulley to a second hanging block, as shown in the diagram. Draw the forces on each body.

Look at the diagram. State in which case the tension in the string is largest.

A spring is compressed by a certain distance and a mass is attached to its right end, as shown in the diagram. The mass rests on a rough table. On a copy of the diagram, draw the forces acting on the mass.

Find the magnitude and direction of the net force in the diagram.

Explain why is it impossible for a mass to hang attached to two horizontal strings as shown in the diagram.

A mass of $2.00 \mathrm{kg}$ rests on a rough horizontal table. The coefficient of static friction between the block and the table is $0.60$. The block is attached to a hanging mass by a string that goes over a smooth pulley, as shown in the diagram. Determine the largest mass that can hang in this way without forcing the block to slide.

A block of mass $M$ is connected with a string to a smaller block of mass $m$. The big block is resting on a smooth inclined plane as shown in the diagram. Determine the angle of the plane in terms of $M$ and $m$ in order to have equilibrium.
