Question

What is a miter saw used for?

Answer 1

Cuts precise angles on wood

Answer 2

Handheld saw to make straight cuts on a variety of materials

Answer 3

makes precise curved cuts for creating furniture and cabinets

Answer 4

Makes precise cuts in large pieces of wood

Answer 5

**Nails**-used for general framing and construction; **Screws**-wood screws, drywall screws, and self-drilling screws; **Bolts**-used to join beams, columns, and other structural members; **Anchors**-expansion anchors (expand when tightened) and sleeve anchors (designed for concrete); **Rivets**-single-use fasteners designed to be a permanent joint between two materials or parts; **Washers**-used to distribute the load of a threaded fastener, such as a screw or nut; **Staples**-attaches structures like insulation, wire, or fabric to surfaces. Fasteners are categorized into 3 types based on their fastening method: **Temporary Fastening**- Fasteners like nuts, bolts, screws, lock pin, and washer are used. These things can be disjointed or joined again easily without any harm to the machine or its parts; **Semi-permanent Fastening**-The fastening may be destroyed but not work. It is used when the joints have had little chance of re-opening. Such as soldering, and riveting; **Permanent Fastening**-They are single-use fasteners designed to be a permanent joint between two materials or parts. When a permanent fastener is used, the parts will never come apart. (rivets, welding, soldering, and brazing).

Answer 6

1: common stud |X (line is marked 3/4" away from center "x" mark 2: header 3: King Stud (X) 4: Trimmer Stud (O) 5: King Stud (X) 6: Sill Plate 7: Criplle Studs / or \ 8: Header 9: Common Stud 10: Bottom Plate 11: Rafter Plate 12: Top Plate

Answer 7

(Length x Width x Depth/Thickness)/27 | Dimensions must be in feet and when solved will convert to cubic yards

Answer 8

1 foot / 12 inches, measures to 12"

Answer 9

1" on the engineer's scale is equal to 40' in real life, measures to 10"

Answer 10

1. Mark the center of the 2x4 2. Depending on the width of the window (**4**x5) divide it by 2 (=2) then take that number and put it on both sides of the center to total the width of the window 3. Mark the studs every 16" (|X - the line being 3/4" from the center/x) and mark studs at the start and end of the 2x4. 4. If studs are placed in the window space mark them as cripple studs ( \ or / , supports the sill plate for the window)

Answer 11

Studs - Forms the walls/holds up roof Floor joists - support the floor, and ceiling weight from the walls Mudsills - Attached to the foundation walls with Anchor bolts, providing a bearing surface that prevents contact btw the untreated floor joists and the concrete foundation. Support Beam - bears the first-floor joists Rim Joists - Rest on the outer edge (on the mudsill) of the mudsills, helps hold the floor joists in a vertical position/part of the floor system Rafter - Beams that make up the roof, and meets at the rafter/ridge beam then the rafter plate which is on the top plate. Sheathing - Used on the floor, wall, and roof

Answer 12

Number of plywood sheets = (total area)/(area of a plywood sheet) area of a plywood sheet = 4'x8'=32ft^2

Answer 13

Black wire: hot wire goes to gold screw White wire: neutral wire goes to silver screw Copper wire: ground wire goes to copper/green screw Red wire: hot wire goes to black screw along with black wire when working on three-way switches 12-2 wire: 12 gauge (bigger than 14), 2 hot wires (not including ground wire) 12-3 wire: 12 gauge (bigger than 14), 3 hot wires (not including ground wire) 14-2: 14=gauge, 2 hot wires (not including ground wire)

Answer 14

3 screws on three way switch-wind ground wires together then put on copper screw, and both black and red go on black screws (doesn't matter which just be consistent with design); 2 screws regular switch-wind neutral wires together then put a nut on it (Ensure that when tightening down screws the wire goes in the same direction the wire is being tightened)

Answer 15

1. Divide length of building by 2 (the number is how many times you should step off with the framing square = 12") 2. mark angle while stepping with frame square 3. at the end account for any overhang 4. At the line before the overhang flip the framing square over so it's facing up/away from you and at the top left of the line (measure the birds mouth by watching the length on the left side of it (skinny side of framing square) (never want it to be 1/3 the width of your board) 5. Be sure to remove 3/4" from the top line/top of rafter to account for the ridge

Answer 16

The Engineer lays out site plans and the architect lays out floor plans

Answer 17

16-penny: Framing, 3" 8-penny: connects sheathing, 2"
