The course is aimed to provide students with real life experience of aircraft manufacturing, assembly and production. Without making any apparent connection to work, introduce students to the pulley. Students will begin exploring the reason the tension of a string connecting a hanging mass to an object will be different depending on whether the object is stationary or accelerating. The pulleys were placed at a level that achieved balance. In the first case of this lab exercise, a cart is attached by a piece of string to another mass which is hung over the table supporting the cart track by a pulley so that as the hangingmass falls, it pulls the cart along the track. 1 Student Workbook P22: Rotational Inertia 012-07000A p.
