How Do You Build A Pulley Car For A Science Project?
A pulley is a system consisting of generally one or two wheels attached by a strap or rope. This system reduces the amount of work needed to lift or move an object. It can also be used to rotate wheels to cause movement, such as in a vehicle. As a science project, students can create a pulley car to study the relationship between movement and pulleys. Using the saw, cut the balsa (for the chassis) to the following dimensions: 6 inches x 2.5 inches. Cut a 1/4-inch-wide piece out of the rear end of the car. Cut this groove parallel to the length of the vehicle, about one inch in length, and down the center. Glue the tube sections onto the wood. Place each piece parallel to the ends, ΒΌ inch in from each end. Project the tubes slightly past the sides of the rectangle, making sure each pair is directly opposite each other. Let dry. Slide the “O” rings over the four pulleys (wheels). Push a rod (axle) through one rear tube section and slip the fifth pulley and a rubber-band onto it before co
