The wooden shoring shown in the illustration is bearing against the hatch coaming and is supporting a load in the direction indicated by the arrows. Which of the following statements is correct for this condition? Illustration SF-0018
AI Explanation
The correct answer is C) Shore "B" will support the load without it cracking.
The reasoning is that shore "B" is positioned at a right angle to the hatch coaming, which provides a stable and secure support for the load. The flat end of shore "B" distributes the load evenly, preventing it from cracking under the pressure. In contrast, shore "A" is not aligned at a right angle, making it more likely to slip or fail under the load.
The other options are incorrect because: A) Shore "A" may not support the greatest load due to its unfavorable angle; B) Shore "A" could still slip under load due to the angled positioning; and D) Shore "B" is less likely to crack at the pointed end since it is designed to bear the load at the flat end.
