An object is supported by a structure when an upward force exerted by the structure balances the downward force of gravity on the object. In this activity, you will attempt to build a structure that will provide a force equal and opposite to the force exerted by gravity on the stack of books. Your task is to design and build a structure or group of structures that will exert an upward force on the books equal to the downward force exerted on the books by the Earth. Only uncooked pasta and masking tape may be used in assembling your structure. The completed structure must support the book a minimum of 5 cm above the table.
