1. Motion TransmissionTransformation

2. Mechanical Systems Combination of 2 or more simple machines Provide mechanical advantage Easier to move loads Transmit/transform motion What is the difference between transmission and transformation?

3. Transmission 4 types of motion transmitted by mechanical systems from one object to another 4 types of motion transmitted by mechanical systems from one object to another

4. Mechanism Type of Motion Example Chain and sprocket CircularBicycle Belt and pulley CircularClothesline GearsCircularWatch Friction wheels Circular Printing press PulleyRectilinearcrane
