When welding bars on sight, special attention should be paid to safety
and ____________. - ✔✔✔ Correct Answer > The exact composition
of the materials to be welded
Explanation:
Not all alloys used in reinforcing bar are compatible.
What is the area of a cylinder that has a radius of 6 inches and height of
8 feet? - ✔✔✔ Correct Answer > 25.12 sq. ft.
Explanation:
To solve for the area of a cylinder, multiply circumference by the height
of the cylinder. Don't forget that the radius is given in inches, but height
is given in feet. Step 1: Find Circumference. Diameter = radius x
2Diameter = 6" x 2 = 12 inches or 1 foot Circumference = D x π (or
,3.14)1 x 3.14 = 3.14 feet Step 2. Find the Area. Area = circumference x
height Area = 3.14 x 8Area = 25.12
What is the minimum spacing of parallel reinforcing bars placed in two
or more layers? - ✔✔✔ Correct Answer > 1 inch
Explanation:
According to the American Concrete Institute, where parallel
reinforcement is placed in two or more layers, bars in the upper layers
shall be placed directly above bars in the bottom layer with clear
distance between layers not less than 1 inch.
What is the maximum spacing of the control joints in a slab that is to
receive a floor finish? - ✔✔✔ Correct Answer > joints are not
necessary
Explanation:
If the carpet, hardwood floor, or other floor finishes are to be installed
on the slab, the control joints are not necessary since the floor finishes
will cover unsightly cracks in the slab.
You have 5 employees that work for eight hours. How much would you
have to pay your employees, if one of them is an apprentice who makes
$17/hour, supervisor makes $33/hour, and three journeymen make
$22/hour? - ✔✔✔ Correct Answer > $928.00
, Explanation:
Apprentice: $17 x 8 hours = $136Supervisor: $33 x 8 hours =
$264Journeymen: 3 x $22 x 8 hours = $528Total: $136 + $264 + $528 =
$928
Finishing with a steel float: - ✔✔✔ Correct Answer > Reduces risk of
cracking.
Please refer to the house plan. How many cubic yards of concrete is
required for the patio (excluding sidewalk), if the slab is 4 inches thick?
- ✔✔✔ Correct Answer > 5.75 cubic yards
Explanation:
Traditional MethodMultiply area of the slab by the thickness of the slab
to get the volume in cubic feet.457 x 4" or .333 = 152.181 cubic
feetConvert cubic feet into cubic yards by diving the cubic feet by
27.152.181 ÷ 27 = 5.6 cubic yards
Industry MethodDivide the area of the slab (sq ft) by 81 to get cubic
yards.457 sq ft ÷ 81 = 5.6 cubic yards
Round up to select the best answer, which is 5.75 cubic yards.
What is the minimum size of anchor bolt can be used in seismic
category D? - ✔✔✔ Correct Answer > #4
