... a molybdenum washer on top of molten alumina, and pulling a fiber by Czochralski-like growth through the orifice in the washer. This floating orifice technique was used to grow several crystals 1 mm in diameter and up to 30 cm long. While effective for research, LaBelle concluded that it would...

... from 316L stainless steel or brass. Sealing is accomplished by mechanically deforming one or more metal (or sometimes PTFE) washers and/or ferrules between the outside surface of a tube and the body of the fitting. The design has advantages for low- and high-vacuum including...

... ( Electrolux, 2010 ). GE has demonstrated smart refrigerators that can shift their defrost cycles; dishwashers and clothes washers that can defer their start time; and electric ovens that can reduce their power consumption when needed ( GE, 2012 ). However, due to their initial high price, it can take a long...

... has achieved this by identifying the location where the pedestal should be placed, putting the fork end there, and then locating a screw hole that is nearby that can hold the fork roughly in place and attaching it with a bolt and washer (do not forget the washer as the forks gall easily, making them...

... washers with a hole about 1.5–2.0 cm in diameter work as a mask if they are large enough to cover the diverging lens’ beveled edges. Use one on each side of the lens. Set up a converging lens, a diverging lens (with its mask attached on both sides), and an object (a bulb in a socket or a candle...

... of the diverging lens. Two washers with a hole about 1.5–2.0 cm in diameter work as a mask if they are large enough to cover the diverging lens’ beveled edges. Use one on each side of the lens. Set up a converging lens, a diverging lens (with its mask attached on both sides), and an object (a bulb in a socket...

... tape, a bulb in a socket, wires, and a battery as was done in the Converging Lens experiment (see Fig. 38.1 ). Be sure to use a diverging lens with the circular mask over each side of the lens. Washers work nicely. Also, be sure that both surfaces of this lens are concave. FIG. 38.1 Finding...

.... 38(TN).1 ]. Be sure to use a diverging lens with the circular mask over each side of the lens. Washers work nicely. Also, be sure that both surfaces of this lens are concave. FIG. 38(TN).1 Finding the focal length of a diverging lens. Procedures A Focal length of a diverging lens using light cone...

...The following activities are presented: Activity 5. Traveling Washer in One Dimension. Activity 6. Traveling Washer in Two Dimensions. Activity 7. Position vs. Time Graphs Using a Motion Probe. Activity 8. Where Am I? Miscellaneous Demonstrations and Activities for Study of Space...

... 2008. The following activities help to answer the question, “Where are you in space?” Activity #5, “Traveling Washer in One Dimension” This activity is appropriate for middle or high school students and is designed to point out the differences among initial position, final position...

... situations these quantities have the same numerical value. (See Traveling Washer activity, p. 30.) The problem arises when they do not have the same numerical value. Understanding this is a major goal of Activity 5, Traveling Washer in One Dimension . You cannot go backward in time, but you can in space...

... bob, or paper clip. The paper clip should be arranged so washers can be slipped on and off the paper clip. The washers play the role of the pendulum bob. The motion of a pendulum is an example of what is called periodic motion (i.e., motion that repeats itself over and over with a regular rhythm...
