Question

Projectiles should not be rolled on the ground, concrete floors, or steel decks but may be rolled on dunnage boards not less than what thickness?

1) 1 inch
2) 2 inches
3) 3 inches
4) 4 inches

Answer 1

Projectiles should not be rolled on concrete floors or steel decks, but on dunnage boards with a minimum thickness.

Step-by-step explanation:

In physics, projectiles are objects that are launched into the air and move in a curved path under the influence of gravity. When rolling a projectile, it is important to consider the surface it is rolled on to prevent damage or accidents. Concrete floors and steel decks are not suitable for rolling projectiles, as they may cause the projectile to deform or bounce unpredictably. Instead, dunnage boards are recommended to roll projectiles on.

The question asks for the minimum thickness of the dunnage boards. Unfortunately, the options provided in the question are missing. However, it is common to use dunnage boards with a thickness of at least 4 inches to ensure stability and prevent damage to the projectile.
