Simple Machines and Mechanical Advantage: Transcript
What is a machine A machine is simply a device that makes doing work easier Even a sloping surface can be a machine Using Machines Mechanical Advantage Even though machines make work easier they dont decrease the amount of work you need to do . 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. . EQ: How do we gain from trade?. What was the most important. document written in 1776?. written by. Adam Smith. The Father of Economics. The Wealth of Nations. He is my great, great, great, great, . Simple Machines. A simple machine has few or no moving parts.. Simple machines make work easier.. With or without a simple machine the work is the same.. Also when simple machines are combined they can make complicated bigger machines.. 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 . 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. IPC Spring . 2014. Energy, Work, Power & Machines. 1. Energy. is the ability to do work. . . Potential energy. – stored energy or energy due to position. . PE=m g h . m. is mass (kg). g. SPS8: Students will determine relationships among force, mass, and motion.. SPS8.e: Calculate amounts of work and mechanical advantage using simple machines.. Work. When a force causes an object to move – work is done.. Pay attention. Simple Machines. Simple machines assist us in doing work by creating a mechanical advantage.. They . do not . change the amount of work; they lower the effort force. There are 6 types of simple machines: lever, inclined plane, pulley, wedge, screw, and wheel and axle.. 2. SIMPLE MACHINES - LEVER. A lever is a rigid bar that rotates around a fixed point called the fulcrum.. The bar may be either straight or curved.. In use, a lever has both an effort (or applied) force and a load (resistant force). . How do you measure mechanical efficiency? Energy, Work and Mechanical Efficiency Mechanical Efficiency Mechanical efficiency is a comparison of the useful work or energy that a mechanical system produces to the work or energy that was put into the system. OBJ. : . Students will determine relationships among force, mass, and motion.. OBJ. : . Calculate amounts of work and mechanical advantage using simple machines.. Work. When a force causes an object to move – work is done.. #The 16th China Beijing International Construction Machinery, Building Material Machines and Mining Machines Exhibition & Seminar#
