Simple deflection

With the softer material and different clamping height we might see significant deflection

The jaw faces will still be parallel to the work piece despite jaw deflection

When we clamp this accurately machined slug at 300 psi and check for deflection

To compensate for this deflection, cutting a slight taper in the jaws may become necessary

Watch yourself. There's a lot of fire coming... from the right side of that deflection tower.

When we clamp the demonstration work piece at a pressure of 400 psi, jaw deflection becomes significant

In this example, each electrical impulse, each deflection on the trace, is caused by a brief pulse of light.

I mentioned different lensing regimes. If the deflection is strong, hence the image splitting, that is called strong lensing regime.

Remove slack in the Belt until the deflection of the Belt has been reduced to between a quarter and three eighths of an inch, or 6 to 10 millimeters

There is some fairly straightforward geometry, that then, you can derive from here, and in the end, you have a quadratic equation that describes the deflection of light rays, in this particular geometrical setting.
