November 25, What are the three types of engine? 2.Where are steam engines primarily used today? 3.What is known as the capacity for doing work and overcoming resistance? U3b- L14 DRILL 1. Internal Combustion, External Combustion, Gas Turbine 2. Power plants 3. Energy

1.Humans and animals use ________ as energy source. 2.What is work? 3.What’s the equation for work? 4.Where is the power developed in an engine? 5.An engine turns _________ motion into _________ motion. U3b- L11 Flight Power Review Food Exertion of a force over a given distance. The cylinder W = F x D (Work = Force x Distance) LinearRotational

Sketch and label the components: W = P = R = C = V = U3b- L11 Flight Power Review Cylinder Wall Piston Connecting Rod Crankshaft Valves

What is engineering? What are the 5 major components to technological systems? Can you represent them in a flow chart? 7 inputs? 3 types of materials? 8 constraints? 4 design principles? Risk analysis, System, Criteria, Constraint, Prototype, Engineering Do you understand the 12 steps of the Design Process? U3b- L11 TEST REVIEW

Listen to instructions first, then get in action: Get your top and get into groups of 4. Designate a recorder and a reporter. Take turns spinning tops (you each get 3 spins total) The recorder times each spin and records it on a clean sheet of paper. When time is called (~5 minutes), reporters will report the longest-spinning top of the group. In front of the class, these top spinners will compete with 3 spins each.
