Mechanical Advantage of a Screw

What are the two factors that determine the mechanical advantage of a screw?

A) The pitch and diameter of the screw

Answer:

The pitch and diameter of the screw are the two factors that determine the mechanical advantage of a screw. The correct option is A) The pitch and diameter of the screw.

When it comes to the mechanical advantage of a screw, the pitch and diameter play a crucial role in determining how the screw performs. The mechanical advantage of a screw refers to how much force is required to turn the screw and how much force it can apply to the object it's working on.

The pitch of a screw is the distance between adjacent threads. A screw with a larger pitch will require less force to turn compared to a screw with a smaller pitch. The diameter of the screw also influences the mechanical advantage. A screw with a smaller diameter will have a higher mechanical advantage as it can exert more force on the object being screwed into or lifted.

Understanding these factors can help in choosing the right screw for the job. Opting for a screw with the appropriate pitch and diameter can make tasks easier and more efficient, ultimately leading to successful outcomes.
