Monday Feb 14th

Today, our objectives were to: (1) Review the simple machines (2) Review how to solve problems involving mechanical advantage

DO NOW:
1. What is one of the objectives of today's class?
2. What simple machine does an AX represent?
3. What is mechanical advantage?
4. You push a box up a ramp 15m. The ramp has a height of 3m. What is the ramp's mechanical advantage?

CLASS WORK:
We will be working on the following "Simple Machines Mini-Project" for the next 3 days. This project will be due on THURSDAY at the beginning of class.

Get a blank piece of paper.

On one side: (a) list all 6 simple machines (b) find pictures in magazines of these machines and glue stick them on. If you don't have any magazines, you can draw the pictures.

On the other side: (a) Define Mechanical Advantage (b) Write the equation for Mechanical Advantage (c) define (in your own words): input force, output force, input distance, output distance (d) Pick one of the problems on pg. 384 in your textbook and solve it.

HOMEWORK:
Solve Monday's problems in HW Packet 3- Machines and Energy.
HW Packet 3 is due FRIDAY 2/18.
