A temporary beam support uses posts every 5 feet over a 35-foot span, including both ends. How many posts are needed?
Correct Answer
A) 8 posts.
Thirty-five feet divided by 5 feet creates 7 spaces; including both ends requires 8 posts.
Why This Is the Correct Answer
Thirty-five feet divided by 5 feet creates 7 spaces; including both ends requires 8 posts.
Why the Other Options Are Wrong
Option B: 7 posts total.
7 posts total. is below the supported result for temporary shoring calculation; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 9 posts total.
9 posts total. is above the supported result for temporary shoring calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 10 posts total.
10 posts total. is above the supported result for temporary shoring calculation; it likely double-counts allowance, uses the wrong unit, or rounds too early.
