The Power Of Mechanical Advantage - Activity - Teachengineering

Each kind has its own mechanism and function that helps make our work simpler by reducing the amount of force we need to exert in order to accomplish a certain job. The ability to control different parameters (such as motor power, testing load and pulley arrangement) enables the teacher, as well as the students, to emphasize and reinforce particular aspects/effects of mechanical advantage. Administer the Pre-Activity Worksheet prior to activity exposure. 3/16" diameter drill bit (appropriate for wood and/or Plexiglas®). Identify a simple machine that uses a fulcrum.

Unit 9 Motion & Force. Upon successful completion of the configuration switch, direct the groups to lower the platform to the ground again. JavaScript isn't enabled in your browser, so this file can't be opened. Critical thinking - apply relevant concepts to examine information about assessing the force amplification attained by machinery in a different light. If necessary, cover the pulley set-ups to avoid having to compete with students' curiosity. Before the Activity. Topics covered include systems, system components, input and output, industries, social and physical systems, gravity, efficiency, work formula, mechanical advantage, automation and more! Please try different filters. Understand what mechanical advantage is determined by for specific simple machines. Ask students to refer to their Pulley Power Worksheet for the tabulated results for their particular group. Figure 4 demonstrates the pulley in use.

Demonstrate that upon execution of the program, the device first prompts for a power setting that is adjustable by turns of the motor-attached wheel. A useful kind of simple machine is an inclined plane and some of these are further classified as wedges and screws. Direct students to modify their systems to Configuration 2. This version of Firefox is no longer supported. The input force - the effort. Information recall - access the knowledge you've gained regarding examples of simple machines and how they operate. Alignment agreement: Thanks for your feedback! Is this content inappropriate? Examples of wedges are: - Knives. Engineers use these skills every day to evaluate the safest and most economical tools for their job sites. A screw is a cylindrical shaft surrounded by ridges called spiral threads. Recognize a simple machine that uses grooved wheels with a rope. For this simple machines science worksheet, students read about simple machines, mechanical advantages, calculating mechanical advantage, output force versus input force, and distance effort versus distance of resistance.

Pulleys are generally used to lift objects, especially heavy ones. Ask the class how groups all changed their set-ups and what the observed effects were. It converts rotational motion to linear motion. Screws are meant for holding things together they also can be used to open up areas. Document Information. Note: Slack should have been taken up by the addition of the two movable pulleys to the system. Ask to students to attempt to lift the platform using the controller brick. Reward Your Curiosity. The classification of levers is based on the position of the fulcrum which in turn effects the effort and force required. After this activity, you will realize that it is just a matter of changing the building materials before we can lift cars above our heads, just like superheroes! Share with Email, opens mail client.
