The main purpose of a joist hanger is to hold a joist 90 degrees to any type of beam as per the building code.  All hangers are to be nailed with specific hanger nails in all available holes.

An imperial ruler is divided into 16ths per inch and bolder lines for balance of fractions up to an inch.

A 16 ounce curved claw hammer is a basic all-purpose hammer used in carpentry.  The others listed are for specific applications.

Clips are used when sheathing roofs framed with trusses due to being 24 inch on center.  The clip holds the plywood from being too weak between spans.

The answer is calculated by subtracting each of the cu.ft. dimensions from the total.
 

PL400 is a construction adhesive used in securing plywood to joist and other wood to wood surfaces.

Stairs are calculated by rise and run for a specific opening. The tread and rise would never be equal.

The answer is calculated by adding two ¼" units or multiplying by 2 to equal 1/2 inch.

It is calculated by 1/16 scale so #10 would be 10/16 inch or 5/8 inch.

This is the narrow channel left behind by the saw and the measure of its width.  Factors are blade, blade teeth and wobble of cut.

Large rectangular objects are squared by either using the 345 method or by taking diagonal measurements.  The framing square is too small for large areas.

12 D common nails are standard fasteners for any 2 by 4,6,8,10,12 application.

Simply multiply 808 x 22.75 to calculate the answer.

If the lumber is 1” wide then it would take 42 pieces to cover the space.  But remember this is nominal size 1” not actual size of ¾.

Divide 22.75 into 96” and your answer will be 4 with 7” left.

Simple subtraction - you need to change 1/16 to 2/32 and then change 9 2/32 to 8 34/32 – 3 15/32 = 5 19/32.

You will need to divide 23'11 9/16 by 2.   Remember you need to change fraction to decimal and decimal to fraction.

The largest number closest to the decimal would be the greatest value.

Add all four dimensions together changing fractions to 16ths to calculate answer.

15' 6 12/16"  + 5' 11 10/16" + 11' 5 7/16" + 6' 9 3/16" =  37'  31 32/16" = 37' 33" = 39' 9"

Add all four measurements.  Total all inches and change to feet before calculating.

 114' 2"
 112' 5"
   88' 3"
+ 97' 6
411' 16" = 412' 4"
 

Multiply 9'6” x 4

4 x 9' = 36'

4 x 6" = 24" = 2'

36' + 2' = 38'
 

If you change all dimensions to 16^th you will find that 3/4” or 12/16” is greater than the others.

A right triangle is half of a square so 10 x 10 would be 100 sq ft divided by 2 equals 50 sq. ft. 

Kickback happens when the saw binds between the two pieces not allowing it to pass completely through.  You should always have one of the pieces free to fall downward on the opposite side you are cutting.  Saw horses would be a good solution.

Multiply 16 x $133.00 and 14 x $157.00 to find the price difference.

A    16 x 133 = 2,128

B    14 x 157 = 2,198
