What tool is primarily used to measure vehicle dimensions during repairs?

  1. Wrench

  2. Frame machine

  3. Impact gun

  4. Measuring tape

The correct answer is: Frame machine

The frame machine is an essential tool in an auto body shop, specially designed for measuring and realigning vehicle dimensions during repairs. When a vehicle has been in a collision, its frame or structure may become distorted. The frame machine allows technicians to accurately assess these measurements and apply the necessary corrections to restore the vehicle's integrity. By using this tool, technicians can ensure that the vehicle's alignment and structure meet the manufacturer's specifications, which is critical for overall safety and performance. While a measuring tape is also a tool used for measurements, it does not have the precision or capabilities of a frame machine, which often incorporates advanced technology to gather accurate dimensional data. Wrenches and impact guns serve different functions, focusing on fastening and loosening components rather than measuring vehicle dimensions.
