Motion TransmissionTransformation
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?
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
