Question 253Safety & Environmental - 1st Asst/Chief70% to pass
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 for this is that the pointed end of shore "B" is bearing against the hatch coaming, which provides a larger surface area for the load to be distributed. This reduces the stress on the wood, making it less likely to crack under the applied load. In contrast, shore "A" has a smaller bearing surface, so it would be more prone to failure.
The other options are incorrect because: A) shore "A" may not necessarily support the greatest load due to the smaller bearing surface; B) shore "A" could still slip under load due to the smaller bearing area; and D) shore "B" may not necessarily crack at the pointed end, as the larger bearing surface helps distribute the load more evenly.
