Example: Free Body Diagrams Determine the tensions in all ropes in the pulley system below. Pulley C is attached at the wall but the other pulleys are suspended. The weights of the pulleys are small compared to the load. Draw the FBD. T A B C 500 kg A simple way to estimate the order of magnitude of the tension would be to draw a diagram (accurate scale) with a straight line from start to finish and two lines to show the shape of the rope with a load on it at about half way. The tension at that position will be about W/(2 SIN(θ)) where W is the load and θ is the angle...

The block with mass m is hanging from a rope that goes over a pulley which is attached to a block of mass M on a frictionless table. So as the block of mass m falls, the rope will pull the block of mass M across the table. They calculate that T= M M+m mg. Now if I set m:=100M, we will then have T= M M+100M 100Mg≈Mg.
