Simple Machines

Simple Machines

Description: Participants will identify, use, and answer questions about simple machines and recognize the relationships between work, force and distance as they apply to each simple machine. Knowledge of the following six simple machines will be demonstrated:  lever, inclined plane, pulley, screw, wheel and axle, and wedge.

How are you going to treat pi since the kids will not be able to bring in calculators?

 

No.  Only simple calculations are necessary and do not require the use of a calculator.  Scratch paper is provided for this purpose.

 

In the case of screws, will you be giving them the pitch?

 In the case of screws, students may be asked to evaluate how a change in diameter, or pitch will change the mechanical advantage.

How will you be handling pi in those instances where it needs to be used?

 

Students will not use Pi in calculations.  They only need to know when a formula for determining mechanical advantage includes Pi.  Students will only be asked to estimate or approximate mechanical advantage.
