Key Answers, Explanations, Notes, and Concepts

61) 50 millimeters length of a piece of lumber is how many decimeter? a. 5 b. 0.05 c. 0.005 d. 0.5

Answer: a. 5
10 millimeters (mm)   = 1 centimeter (cm) 10 centimeters             = 1 decimeter (dm)     = 100 millimeters 10 decimeters              = 1 meter (m)             = 1,000 millimeters 10 meters                   = 1 dekameter (dam) 10 dekameters             = 1 hectometer (hm)  = 100 meters
62) How tall is a 10 meter building in inches? a. 3.937 b. 39.37 c. 393.7 d. 3,937

Answer: c. 393.7

1 meter = 39.3701 inches 63) A carpenter wants to measure long distances. Which tool is appropriate? a. Ruler b. Extension rule c. Meter stick d. Pull-push rule

Answer: d. Pull-push rule

Ruler- a tool or device used to measure length and draw straight lines.
Extension rule- a sliding attachment to a folding rule for the measuring of inside distances between objects.
Meter stick- is a measurement tool that measures one meter (hundred centimeters) and is used to measure things in meters and centimeters. Things like the length of a table or the width of a bag can be measured using a meter stick.

Pull-push rule- comes in lengths from five or six feet up to twenty-five feet. It can also be purchased in metric lengths. The blades (as the tapes themselves are formally known) come in hall- inch, three-quarter-inch, and one-inch widths.

64) A carpenter wants to mark very rough objects. Which tool is appropriate? a. Chalk line b. Extension rule c. Level d. Border line
Answer: a. Chalk line

Chalk line- a tool for marking long, straight lines over distances onto the surface of an object to provide accurate guides where using a ruler or straight edge tool would be impractical.
Extension rule- a sliding attachment to a folding rule for the measuring of inside distances between objects.
Level- a tool used to determine whether a surface is horizontal (level) or vertical (plumb). Without this, you can't build a house that works well or looks good—not to mention hang kitchen cabinets or trim out a door.
Border line- there is no such
65) A carpenter wants to obtain vertical line. Which tool is appropriate? a. Ruler b. Level c. Plum bob d. Pull-push rule

Answer: c. Plum bob
Plum bob- is a pointed weight attached to the end of the string and is used to find a vertical reference line called plumb. Plumb is the vertical equivalent to a spirit level. Plumb bob has been around for thousands of years, dating back to Ancient Egypt.
66) A carpenter wants to cut lumber across the grain. Which tool is appropriate? a. crosscut saw b. rip cut saw c. back saw d. hacksaw

Answer: a. crosscut saw

crosscut saw- is any saw designed for cutting wood perpendicular to (across) the wood grain. Crosscut saws may be small or large, with small teeth close together for fine work like woodworking or large for coarse work like log bucking, and can be a hand tool or power tool.Crosscut saws for cutting across the grain.


rip cut saw- are used for cutting wood with the grain, crosscut saws for cutting across the grain. The main difference between the saws is in the way the teeth are ground.
back saw-
backsaw- is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery.

hacksaw-is mainly used for cutting thin metal such as aluminum, brass, steel, or copper. Hacksaws are also used for cutting plastics such as PVC, PEX, or ABS on pipes or on sheet goods made of PVC, polystyrene, and more. A hacksaw should not be used for cutting wood or stone
67) A carpenter wants to fasten and remove nails. Which tool is appropriate? a. Hammer b. Ballpeen hammer c. Claw hammer d. Sledgehammer
Answer: c. Claw hammer
Hammer- a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object.
Ballpeen hammer-Besides for peening (surface hardening by impact), the ball-peen hammer is useful for many tasks, such as striking punches and chisels (usually performed with the flat face of the hammer). The peening face is useful for rounding off edges of metal pins and fasteners, such as rivets.
Claw hammer-is a hammer primarily used in carpentry for driving nails into or pulling them from wood.
Sledgehammer- is a tool with a large, flat, often metal head, attached to a long handle. The long handle combined with a heavy head.
68) A carpenter wants to smoothen wood surfaces. Which tool is appropriate? a. File b. Sandpaper c. Back saw d. Plane

Answer: d. Plane
File- s a tool used to remove fine amounts of material from a workpiece. It is common in woodworking, metalworking, and other similar trade and hobby tasks

Sand paper- mainly to sand metal surfaces i.e., to remove rust or to sand drywall to smooth joints. It allows for wet sanding using water as a lubricant. And while it also can be used to sand between coats of finish, it's not typically used for woodworking.
backsaw- is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery.
Plane- is a cleverly hafted cutting edge, the function of which is to skin or shave the surface of wood. Used to finish and true a surface by removing the marks of a previous tool (adz, ax, or saw), a plane leaves the surface smooth, flat, and straight.

69) A mason wants to create a smooth finish of concrete after floating. Which tool is appropriate? a. Brick hammer b. Concrete trowel c. Plane d. Float
Answer: b. Concrete trowel
Brick hammer- is one of the most popular and used tools in a mason's tool setup. It can be used for cutting, cleaning and setting bricks, stone or masonry. The two sides of the head are very different from each other and for good

Float- is a tool used to finish a concrete surface by making it smooth. A float is used after the surface has been made level using a screed. In addition to removing surface imperfections, floating will compact the concrete as preparation for further steps.

70) A mason wants to set or cut brick, block, or stone. Which tool is appropriate? a. Claw hammer b. Crandall c. Mason's hammer d. Star drill

Answer

Claw hammer-is a hammer primarily used in carpentry for driving nails into or pulling them from wood.
Crandall- Hand tool of a stonecutter to hammer away the irregularities on a hard stone face. It is composed of a number of pointed irons, held together in a bracket with a locking wedge. The handle can be wood or metal.

Mason's hammer- also known as Brick hammer- is one of the most popular and used tools in a mason's tool setup. It can be used for cutting, cleaning and setting bricks, stone or masonry. The two sides of the head are very different from each other and for good

Drafting Notes

Image
  Resource: PNU- TLE Drafting Concept of Drafting  In most cases before making the final plan it takes the form of sketches and drawing  Sketches usually precede the making of scale drawing of an object.  An attempt to make something without having a definite plan usually results in waste of materials and time as well as in a poorly constructed project. DRAFTING EQUIPMENT In order to do planning or drafting work it is first necessary to learn the names of the tools the draftsman uses and the way he uses them to produce a good drawing. In addition it is necessary to learn certain rules and regulations which are the principles of good drafting.  Drawing Pencils - Drawing pencils is made of a much better grade of graphite, commonly called lead, than the ordinary writing pencils so it is possible to draw lines which are of uniform blackness and to do better quality of line work. - The hardest of the drawing pencils is the 9H. The next hardest in order are the 8H, 7h, 6H, 5H, 4H, 3H, 2H
