Conduit Bending Flashcard

Front

What is the recommended action to prevent injury while bending metal rods on a construction site?

Back

Always wear protective gear

Answer explanation

Always wearing protective gear is crucial when bending metal rods to prevent injuries from potential accidents, such as flying debris or sharp edges. This choice prioritizes safety on the construction site.

Front

Which tool should Samuel use to ensure a shelf is perfectly horizontal?

Back

Klein Tools Level

Answer explanation

To ensure a shelf is perfectly horizontal, Samuel should use a Klein Tools Level. This tool accurately indicates whether a surface is level, unlike the other tools listed, which are not designed for this purpose.

Front

What should be done if the two legs of the U are skewed?

Back

Correct the alignment of the legs

Answer explanation

If the two legs of the U are skewed, the correct action is to correct the alignment of the legs. Ignoring the skew or adjusting the bend angle will not resolve the misalignment.

Front

How is the choice of degree for an offset bend usually determined?

Back

By the installer’s choice and installation location

Answer explanation

The choice of degree for an offset bend is primarily determined by the installer’s choice and the installation location, as these factors influence the required angle to navigate obstacles and achieve proper alignment.

Front

Formula to calculate the Total Shrink in the conduit bending process?

Back

(Offset Distance) X (Shrink/Inch)

Answer explanation

The correct formula to calculate Total Shrink in conduit bending is (Offset Distance) X (Shrink/Inch). This accounts for the shrinkage per inch multiplied by the distance offset, providing an accurate total shrink value.

Front

How do you calculate the First Mark Distance on the conduit?

Back

(Distance to Obstacle) + (Total Shrink)

Answer explanation

To calculate the First Mark Distance on the conduit, you add the Distance to Obstacle and the Total Shrink. This accounts for both the initial distance and any adjustments needed due to shrinkage.

Front

If the center angle is 45°, what will the two return bends be?

Back

22.5°

Answer explanation

To find the return bends for a 45° center angle, divide the angle by 2. Thus, 45° / 2 = 22.5°. Therefore, the two return bends will each be 22.5°, making this the correct choice.

Front

Where should the Center of Bend Rim Notch be positioned?

Back

On the center mark

Answer explanation

The Center of Bend Rim Notch should be positioned on the center mark, as this ensures proper alignment and functionality of the conduit. The other options do not provide the correct positioning for optimal performance.
