The correct answer is: A screw allows the force to be applied in a more convenient direction.
When comparing a screw to a nail, one advantage of using a screw is that it allows the force to be applied in a more convenient direction. This is because a screw has threads that wrap around its shaft, resembling a spiral ramp. When a screw is driven into a material, like wood or metal, these threads grip the material and create a rotational force. This rotational force allows the screw to be easily turned with a screwdriver or power tool, applying force in a convenient direction.
In contrast, a nail is a smooth, cylindrical object that doesn't have threads. When a nail is hammered into a material, it relies on the force of the hammer strikes to push it into the material. The force applied to a nail is primarily in a linear direction, perpendicular to the material's surface. This linear force might not always be the most convenient or effective direction for certain applications.
To verify this answer, you can conduct a simple experiment. Take a screw and a nail, and try driving them into a scrap piece of wood. Observe how the force is applied and the direction in which each fastener moves. You will notice that the screw can be easily turned with a screwdriver, allowing for more control over the force and direction, while the nail can only be hammered straight in, limiting its options for force direction.
