Analysis

​Requirements

• The cost of parts for the Baja car should be limited to $400.

• The Baja Car must be able to withstand being dropped from 1.5 feet.

• The chassis will weigh less than 7 pounds.

• The suspension will be able to handle at least 100 N of force when dropped on its tires.

• Full suspension travel of 2” without interference.
