Down: 1) places the fulcrum (pivot point) between the effort and the resistance forces. Effort and resistance forces are applied to the l arm in the same direction, and it is the only class that can have a mechanical advantage greater than or less than one. It always changes the direction of force. 2) is a flat surface set at an angle, or incline, with no moving parts. It allows for objects to be lifted by pushing or pulling the load. 3) rotate together as a simple lever to lift or move a load. The effort force can be applied to either on or the other and transfers a rotational force from one to the other. It is important to know to which component the effort force is applied. 4) is a wheel with a groove in its rim that changes the direction and/or magnitude of a force exerted by a rope (or a similar length of material that can be looped over). There are two types 5) the fulcrum is located at one end of the lever, with the effort force (input force) between the fulcrum and resistance force. In this type , the resistance and effort forces are in opposing directions. It does not change the direction of force but always produces a gain in speed and distance and a decrease in force. It always has a mechanical advantage of less than one.7) A representation of a real-world situation or system using mathematical concepts and language.9) Impeding effect exerted by one material object on another.10) has an axle in a movable block and is supported by two parts of the same rope. It can translate and move when the rope is pulled.11) is a rigid bar free to rotate on a fulcrum. On one end, a force is applied. On the other end of , a load is lifted. There are three classes. 13) includes all the realities that can cause a machine to lose energy when solving for mechanical advantage Across: 6) Fixed and movable pulleys, in combination, provide mechanical advantage and a change of direction for effort force. 8) is the energy transferred when a force F is applied to an object moving through a distance d. 12) The greatness of size or amount.14) ignores all the realities that can cause a machine to lose energy when solving for mechanical advantage 15) The ratio of the force produced by a machine to the force applied to it and is used in assessing the performance of a machine. 16)  is made of two components: an inclined plane wrapped around a cylinder, forming the path and pitch, and a wheel and axle used to create rotary motion. It changes rotary motion into linear motion and has a large mechanical advantage.17) places the resistance force (load) between the fulcrum and the effort force. In this type , the resistance force and effort force are in opposing directions, and the direction of force does not change. It always has a mechanical advantage greater than one.18) has an axle attached to a supporting structure that does not move and changes the direction of the force. 19) A machine made up of two or more simple machines. 20)  functions as a moving inclined plane that tapers to a thin edge and is used for splitting or raising heavy bodies or for tightening by being driven into something.
