Question 1928 Deck Safety

The correct answer is C) Reduces plate stress. Welded butt joints in the shell plating do not reduce plate stress compared to other construction methods. In fact, welded joints can introduce stress concentrations and increase the overall plate stress, which is a disadvantage. The other options are advantages of using welded butt joints - A) reduces weight, B) maintains tensile strength at the joints, and D) reduces frictional resistance. However, the reduction in plate stress is not an advantage of this construction method.
