Using The ProtractorMechanisms

A protractor can help you measure and align the angles of your propeller or turbine blades. It can also be used to measure mechanisms such as the lever arm on rubber band racer or mousetrap vehicle.

Measure angles of turbine blades and propellers.

Find lever angles on vehicles and other mechanisms.

To measure angles:

Align the hub edge parallel with the protractor edge.

Align the connector strip edge paral-lel with the protractor edge.

Set the protractor notch onto the pivot point (dowel, skewer or tooth pick).
