  1. formula for board feet
    how long (running feet) x how wide (type of wood) / 12 so simplified: running feet x width / 12 * type of wood means if you are using 2x4 lumber, your wood width is 4.
  2. running feet
    how long the boards are end to end if you line them all up. get running feet by adding up the length of each piece of wood.
  3. cut list for a 4x8 platform
    • Rails: 2 @ 4'
    • stiles: 2 @ 7'-9"
    • toggles: 3 @ 3'- 9"
  4. what increment are toggles placed on flats? what about platforms?
    • every 4 ft on flats
    • every 2 ft on platforms
  5. what kind of wood is used to top a flat?
  6. what type of wood are platforms made out of?
    2 by 4

    1 by 4
  8. what is 3/4" plywood used for?
    platform tops
  9. what is the cut list for a 4 x 10 flat?
    • rails: 2 @ 4' (rails are ALWAYS 4 ft on this test)
    • stiles: 2 @ 9' - 10 1/2 "
    • toggles: 2 @ 3'- 10 1/2" (this will ALWAYS be toggle measurement for flats)
  10. what are the properties of light
    • intensity
    • color
    • movement
    • distribution (like angle, focus, hard/soft edge, etc)
  11. circuits
    2 types; Parallel- a bunch of wires connecting the lights Series- one wire connecting the lights
  12. Ellipsoidals
    • also called Source four or ERS

    • mounted close to stage
    • short and square
    • 1 lense soft light
  15. Dimmer
    controls the amount of electricity sent out
  16. circuit (in a lighting system)
    • pathway for electricity to flow
    • outlet in the wall
    • number that you plug the light into
  17. channel
    • how the lightboard talks to the system
    • controls the dimmer
  18. standard voltage
    120 volts
  19. W=VA
    • W is watts
    • V is volts
    • A is amps
    • W= 120 * amps
  20. 1. Cable
    2. Jumper
    3. 2 -fer
    • 1. extention cord with a plug that you can plug into the light system (usually not Edison)
    • 2. cord that is 5 feet or less
    • 3. lets you plug 2 instruments into one
  21. watts
    the actual power
  22. amps
    flow of electricity or power
  23. dimmer capacity
    how much wattage you are able to have on the dimmer
  24. volts
    potential power and pressure
  25. intensity
    how bright something is
  26. dimmer load
    how much wattage you actually have on the dimmer
  27. gobo
    light pattern that you insert into an ERS it is a type of "color media"
  28. gel
    colored plastic this is a type of "color media"
  29. What is the difference between the line connector and the load connector?
    • the load connector is the plug on the instrument (male plug)
    • the line connect is the outlet in the wall pocket, connector strip, or on the back of the dimmer pack (female plug)
  30. types of connectors used
    • 20 amp stage pin (the square kind we use in Belk, 3 prongs)
    • 20 amp twist lock (round kind with 3 prongs)
    • 15 amp edison (normal plug)
  31. what wire colors are hot, grounded and neutral?
    • ground wire is green
    • Neutral wire is white
    • hot wire is black
  32. soft patching
    hard patching
    soft patching- do it on the light board with the computer hard patching- physically plug the lights in
  33. random patching info
    • •contains one plug for every permanently installed stage circuit and one or more outlets for every dimmer.
    • •A patch panel is installed when the lighting system contained a large number of stage circuits but only a few dimmers.
  34. alternating current
    direct current
    • electricity used with batteries
    • electricity from the wall
    • Clockwise current is positive, counter-clockwiseis negative
  35. McCandless Method
    • theory of lighting plots to recreate 3:00pm
    • 45° angles
    • warm and cool lights
    • Key light- brighter light, main source
    • Fill light- filling in the shadows, lower light
  36. Hue
  37. primary color
    color you cant mix
  38. 3 primary colors of light
    • red
    • blue
    • green
    • these 3 together create white light
  39. 3 primary colors (when painting etc)
    • Magenta
    • Cyan
    • Yellow
  40. value
    • the amount of black or white in the color
    • tint is adding white
    • shade is adding black
  41. saturation
    amount of grey in the color
  42. subtractive mixing
    subtractive mixture
    • pigment in paint
    • mix all colors together and get black
  43. additive mixture
    mixing colors of light, creates white light
  44. Color wheel
    3 types of color
    • primary
    • secondary
    • tertiary

    complementary colors are on opposite sides
  45. 3 basic components of paint
    • Pigment- what gives paint its color (like berries or something)
    • Vehicle- holds binder and pigment together (water/oil)
    • binder- holds pigment to the surface of what you're painting (latex/vinal)
  46. true/false
    when mixing colors you should add the white into the dark color
    • FALSE
    • when mixing paint you should add the dark color into the white
  47. how much paint should you use on your paintbrush?
    dip the bristles 1/2 way into the paint
  48. proper way to clean a brush
    • with murphy oil soap
    • use a wire brush
    • rise it out until the water is clean
  49. types of painting textures
    • dry brushing (little paint on brush)
    • spattering (splatter paint)
    • lining (drawing lines)
    • glazing (watery paint)
    • stippleing (dab brush)
    • scumble (criss cross different colors on top of each other)
  50. Rigging
    • •Cable clamp
    • –U-bolt, Saddle, Nuts
    • –Never Saddle a Dead Horse: the live part is the part with tension
    • Rating: ropes are rated by tensil strength
    • Hemp: made of plants, pretty strong
    • nylon: stretches a lot
    • Wire: also airplane cable, strongest
    • monofilament: fishing line! (spiderwire is black fishing line)
