Mechanics Cams & Cranks Kit
Hands-on projects introduce students to the importance of cams and cranks moving everyday machines. Students learn how the position of a handle or crank affects the amount force needed to lift items on a crane. They also discover how different types of motion from cams affect the speed of an oil pump or sewing machine. Through trial and error, students learn how to transmit power and convert reciprocal motion into rotational motion. Detailed guide fully explains how to build 8 machines the scientific principle applied in each project. Kit includes 111 pieces. Recommended for Elementary and up.
