Conduit Level 1 Practice Test

Think of locating the center along the saddle’s centerline. Because the three-bend saddle is symmetric, the center lies exactly halfway along the centerline from left end to right end. So the distance from the left end to the center is half of the total length along the centerline. To find that total length, add up the straight portions and the contributions from the bends. Each 90-degree bend with radius R contributes an arc length of (pi/2)·R to the centerline. With three such bends, the bend portions sum to (3·pi/2)·R. Adding the straight-section lengths shown in the diagram gives the full centerline length. Using the given dimensions in the problem, the total centerline length comes out to 89 1/4 inches. Half of that is 44 11/16 inches, which is why that option is correct.
