Answer :
Final answer:
The distance to Mark 1 for a three-bend saddle with a 4-inch rise and using a 45° center bend multiplier of 2.6 in 1 1/4-inch RMC is 10.375 inches (10 and 3/8 inches) when rounded to the nearest eighth of an inch.
Explanation:
To calculate the distance to Mark 1 for a three-bend saddle in 1 1/4-inch RMC (Rigid Metal Conduit), we will use the given rise of 4 inches with a 45° center bend and a multiplier of 2.6. The distance to the first mark, also known as the 'stub up' length for the bend, is determined by multiplying the rise of the obstacle by the chosen multiplier for the angle of the bend. Since our rise is 4 inches and our multiplier for a 45° saddle is 2.6, we calculate the distance to Mark 1 as follows: Distance to Mark 1 = Rise × Multiplier = 4 inches × 2.6 = 10.4 inches.
However, it is often necessary to round the result to the nearest eighth of an inch to conform to typical measuring tools used in conduit bending, making the final distance to Mark 1 10.375 inches (10 and 3/8 inches). The distance to Mark 1 for a three-bend saddle with a 4-inch rise and using a 45° center bend multiplier of 2.6 in 1 1/4-inch RMC is 10.375 inches (10 and 3/8 inches) when rounded to the nearest eighth of an inch.
