1st Class Lever - Fulcrum located between R and F R & F in the same direction F + R=Fulcrum MA depends on the location of the fulcrum MA=1 *Atlanto-occipital joint 2nd Class Lever - F<R Advantageous in terms of force (MA>1) Most levers used in daily life *Ankle in tiptoeing 3rd Class Lever - F>R Disadvantage in terms of force (MA<1) Majority of the human body joints (95%) Advantage in displacement and speed and the main source of human mobility *Elbow in lifting 6 join...

Classes of Levers - Class 1, Class 2, Class 3 Class 1 Levers - Fulcrum is in the middle, with the effort (input) force on one side of the fulcrum and resistance (output) on the other side. Mechanical Advantage greater or less than 1 Ex: Seesaw, Crowbar, Pair of Scissors. Class 2 Levers - Resistance is in the middle, the effort is applied on one side of the resistance and the fulcrum on the other side. Mechanical Advantage always greater than 1 Ex: Wheelbarrow, nutcracker, bottle opener, ...

How do inclined planes work? An inclined plane allows you to exert your input force over a longer distance. As a result, the input force needed is less than the output force. Simple Machine Is the most basic device for making work easier. What are 3 closely related simple machines from the inclined plane family? Inclined plane Wedge Screw What is a ramp an example of? A ramp is an example of a simple machine called an inclined plane. Inclined Plane Is a flat, s...

What is a lever? CORRECT ANSWER A lever is a simple machine which provides a mechanical advantage in carrying loads. What comprises a lever? CORRECT ANSWER A lever comprises a fulcrum, which is a hinge or a pivot, and a beam or a rigid rod. What forces are applied to the beam of a lever? CORRECT ANSWER The input force, or the effort, and the output force, which carries the load. What happens to the input force applied to the beam of a lever? CORRECT ANSWER The input force is converted ...

kinematics - Answer-description of motion including planes of motion, type, and the direction of the motion kinetics - Answer-study of motion and it's causes like gravity and muscles center of gravity - Answer-the point around which an object's weight is evenly distributed. It can change when a person raises their arms or jumps line of gravity - Answer-imaginary vertical line that passes through the center of gravity. If it is located in the person's base of support, then the object is ...
