A motor vehicle is a complex machine that is composed of many simple machines. Regardless of complexity, in order for these machines to function properly, they require many parts working together. To ensure a vehicle functions properly many measurements are taken during the planning stages of the vehicle design, to the assembly manufacturing line, and finally to the operation of the vehicle in the owner’s hands. Think of some measurements associated with a vehicle.

 

In this lesson you will explore the precision, accuracy, uncertainty, and tolerance of measures related to a vehicle. You will also learn about some of the benefits and limitations of these measures.

 

Lesson Outcomes

 

At the end of this lesson you will be able to

  • solve a problem that involves accuracy, precision, or tolerance
