An offset is to be fabricated in a 3/4-inch RMC to extend from the 3/4-inch knockout in the box at the left, over the obstruction at the right, and down onto the surface below. The offset will be pre-positioned using the radius adjustment so that it clears the obstruction.

If you were to lay out the offset for 10° bends, how far from the left end of the conduit would Mark 1 be placed? Keep in mind that you must accommodate the amount of thread that will be needed inside of the box.

Note: The values calculated for this question may be used for additional questions. (Round the answer to the nearest eighth inch. Answer the question in the form of a decimal.)

Distance to Mark 1 = ?

Answer :

Final answer:

To calculate the distance from the left end of the conduit to Mark 1, use the formula Length of Offset = Radius * tan(Bend Angle) and add the amount of thread needed inside the box.

Explanation:

To calculate the distance from the left end of the conduit to Mark 1, we need to consider the length of the offset and the amount of thread needed inside the box. The offset is in the form of a 10° bend, so we can use trigonometry to find the length of the offset. The length of the offset is equal to the radius of the conduit multiplied by the tangent of the angle of the bend.

The formula to calculate the length of the offset is: Length of Offset = Radius * tan(Bend Angle)

After calculating the length of the offset, we need to add the amount of thread needed inside the box, which is the length of the knockout minus the radius of the conduit. Therefore, the distance from the left end of the conduit to Mark 1 is the length of the offset plus the amount of thread needed inside the box.
