Inclined Plane Definition A slanting surface connecting a lower level to a higher level How it makes work easier It is used to help things move up or down distances Examples Ramps stairs slide escalator slope.

November 24. th. -25. th. . Goal:. I will be able to explain the relationship between mass, force and distance traveled. . I will be able to describe the difference between different simple machines. . A. 5. th. Grade Smarty Pants?. Simple Machines Song. A bar that turns against . an unmoving point is called a…. Wheel and Axel. Lever. Pulley. Wedge. Video. A bar that has an inclined plane wrapped around it is called a…. WORK. Mechanical Advantage. Force. Effort. Efficiency. 1. Goals. Analyze the simple machines . qualit. atively and . quant. itatively in terms of force, distance, work and mechanical advantage. Be able to calculate mechanical advantage. Work. Work is done when a . force . (push or pull) causes an object to move in the . same direction . that the force is applied.. Formula: Work= Force x Distance . (W = F x D). If there is no movement, there is no work.. Pulleys. The Big Idea of this Investigation. A simple machine is a mechanical device that makes work easier by magnifying, modifying, transferring, or changing the direction of applied force. Simple machines are the elementary "building blocks" of which all complicated machines are made.. If we did not have the large machines that we have today for building, would we still be able to make these large structures? Why?. 2. Essential Question:. How do simple machines make life easier for us?. Simple machine is a term used to describe certain parts and pieces.. A simple machine is an apparatus that is made of a small number of pieces and permits us to use more efficiently or more comfortably mechanical energy. It helps us reduce the necessary force to perform a task.. A simple machine is any of the basic mechanical devices for applying a force, such as an inclined plane, wedge, or lever.. Simple machines are utilized to reduce the amount of force required to perform work, initiate or resist motion, break or split molecular bonds of solids, or keep two non-molecularly-bonded solid objects bound together.. Physical Systems: Simple Machines. Simple Machines. A simple machine is a device, composed of only one or two parts, that requires a single force to work.. The stapler works by applying a single downward force at its open end. . Why do we use machines?. Machines make doing work easier.. But they do not decrease the work that you do.. Instead, they . change the way you do work.. In general you trade more force for less distance or less force for more distance. including Finite State Machines.. Finite State MACHINES. Also known as Finite State Automata. Also known as FSM, or State . Machines. Facts about FSM, in general terms. Finite State Machines are important . #The 16th China Beijing International Construction Machinery, Building Material Machines and Mining Machines Exhibition & Seminar#
