🔍 Key Concepts

• Relationship between force, area, and pressure in basic physics • How spring force is applied to the brush face in a DC motor • Units typically used for pressure (e.g., pounds per square inch) vs units for force and area

💭 Think About

• Which quantity in the choices represents a force and which represents an area? • In physics, when you want to find pressure, do you divide force by area, or area by force? • Look at the words pressure and force in the options—are they being used in a way that matches the standard pressure formula?

✅ Before You Answer

• Verify the basic physics formula: Pressure = Force ÷ Area • Confirm which term in the problem corresponds to force (spring) and which corresponds to area (brush contact area) • Eliminate any options that use subtraction instead of a division relationship between force and area
