When I was an undergraduate physics student many years ago, I did some experiments with bouncing balls. I tried to analyse the problem theoretically, but did not succeed. I could, however, analyse the bouncing of shapes of uniform cross section, like a rectangular block.

Assume a rectangular body falls to the ground vertically. Think of a rectangular rubber eraser falling down upon a stone slab.

We disregard air resistance. At moments A and B, the block is still in free fall. C is the moment when it hits the ground. The top goes right on falling! Not for long, however. The bottom of the block does feel the impact.

It goes into a stressed and compressed state, indicated by red in the picture. A shock wave moves up through the block at the speed of sound i. At the moment E, the compression wave has reached the top of the block.

Now every particle in the block is momentarily standing still; all kinetic energy has been transformed into potential i. At the moment G, the decompression wave has hit the ground. The block is now again unstressed, and moving upwards as a whole. By putting some numbers into this, and using the formula for the speed of longitudinal sound in solids, it is easy to deduce, in the case of a perfectly elastic block: With which force the block hits the ground e.

Which stress is experienced by the block and also which strain, in the case of a perfectly linearly-elastic blockand of course also how much greater this is than the stresses in the block when it it is resting on the ground statically.

That this really makes sense: All the essential physics has already been mentioned above. Duration of the impact The most remarkable thing about the impact of a rectangular block or a cylinder is that the region behind the shock front red in the picture is uniformly stressed.

I remember how amazed I was when I discovered this. I found it by some complicated reasoning involving Fourier series. For the time being the reader should just take this on faith.LaTeX Math Symbols Prepared by L.

One end of the catheter will sit in your small intestine, and the other will come out of your body and will be attached to a drainage bag (see Figure 3). The name says it all, folks.
