A bolt is threaded onto one end of a thin horizontal rod, and the rod is then rotated horizontally about its other end. An engineer monitors the motion by flashing a strobe lamp onto the rod and bolt, adjusting the strobe rate until the bolt appears to be in the same eight places during each full rotation of the rod (Fig. 6-9). The strobe rate is 2000 flashes per second; the bolt has mass 40 g and is at radius 5.0 cm. What is the magnitude of the force on the bolt from the rod?
Because the rod can be seen 8 times in one rotation, it is rotating at 2000/8 = 250 rotations/sec.
F = ma, for circular motion becomes F = mv²/r
velocity of bolt = 250 * 2πr / sec. because it goes around the circumference of a circle 250 times in a second.
Note that because you are using grams and centimeters your force will be in dynes.

Motion Lamp What Are Those Lamps Called That Look Like The Pixar Lamp?
I do stop motion and I need a light source. I have seen lamps like this in the store. What are they called?
It's called an Anglepoise Desk Lamp -
This is from Wikipedia -
The only characters are two Anglepoise desk lamps, one large and one small, inspired by a Luxo brand task-light on John Lasseter's desk (hence the title). Luxo Jr. (small) plays with a small inflated rubber ball, chasing it and trying to balance on it, as Luxo (large) reacts to these antics. The ball eventually deflates due to Luxo Jr. jumping on it; Luxo Jr. is admonished by Luxo, then finds and plays with an even larger ball.[2]

motion lamps with Pat Metheny and scantily clad Rockettes
I bought a lamp motion detector to plug my lamp into. I have noticed the lamp will come on quite frequently for short periods of time when no one is in the room. Is there something I can do to stop this?
Check for drafts of warm air, anything that might simulate a human body moving. If your detector has a sensitivity control you can de-tune the sensor. If not and the problem is with a heat supply, try masking off the lens section looking at the heat. Try a piece of masking tape first just to see if you have a solution. If that works, cut the shape neatly and stick it in place. You may also be able to redirect the sensor.
Beware cats and dogs and false signals.
