3. how does the torque delivery (feel or sound) differ when using an impact driver instead of a drill, and…

Brief Explanations:

An impact driver delivers torque in short, high - force bursts, creating a distinct 'hammering' feel and sound. A drill provides continuous torque. The bursts in an impact driver allow it to overcome high - resistance fasteners better, reducing user fatigue and preventing stripping. This distinction is important as it makes impact drivers ideal for tasks like driving large screws or removing stubborn bolts, while drills are better for precision work and softer materials.

Answer:

An impact driver delivers torque in short bursts with a 'hammering' feel and sound due to its internal mechanism. This allows it to handle high - resistance fasteners well. A drill provides continuous torque, better for precision and softer materials. The distinction is important as it determines the tool's suitability for different fastening tasks.
