How many straps are required if they are placed every 8' for a specified run?

To determine the number of straps required when placing them every 8 feet over a specified run, one must first understand how to calculate the intervals and the length of the run.

When a strap is placed every 8 feet, it effectively means that for every 8 feet of linear distance, there will be a strap installed. If, for example, the total run is 440 feet, one would divide this 440 feet by 8 feet to find the total number of 8-foot intervals, which equals 55.

However, it’s important to remember that the first strap is typically placed at the starting point (0 feet). Therefore, while the number of intervals gives you the number of straps between the beginning and the end of the run, you add one additional strap at the start to account for the beginning of the run.

Consequently, if your calculations reflect a total of 55 intervals from 0 to 440 feet, you include the initial strap, leading to a total of 55 straps required when placed every 8 feet.

This reasoning confirms that the correct answer is the total of 55 straps, illustrating the necessity of including the strap at the starting point in the final count.
