Question 237General Subjects - QMED

The correct answer is B) steel rule. To set the dividers to the proper radius, you should use a steel rule. A steel rule is a precise measuring tool that can be used to accurately set the dividers to the desired radius. The markings on the steel rule allow you to easily measure and adjust the dividers to the required size. The other options are not the correct tools for this task. A caliper (A) is used for measuring the dimensions of an object, not for setting the radius of dividers. A micrometer (C) is a precision measuring instrument used for very small measurements, not for setting divider radii. A scribing circle (D) is a tool used for marking circles, not for adjusting the span of dividers.
