🔍 Key Concepts

• Relationship between pulley diameters and rotational speeds (rpm) in a belt drive • Using the speed ratio formula: driver speed × driver diameter = driven speed × driven diameter • Identifying which is the driver (motor) pulley and which is the driven (compressor flywheel) pulley

💭 Think About

• Which pulley (motor or compressor flywheel) is turning faster, and should that pulley be larger or smaller? • How can you use the known diameters and speeds to set up a proportion to solve for the unknown pulley diameter? • After solving, which choice is closest to the calculated value and still makes sense physically?

✅ Before You Answer

• Confirm you know that the motor is the fast-rotating driver at 1750 rpm and the flywheel is the slower driven at 510 rpm • Write and rearrange the basic belt drive relation: (speed₁ × diameter₁) = (speed₂ × diameter₂) and solve for the unknown diameter • Check that the final pulley size is smaller than the flywheel (because it turns faster) and matches one of the listed options
