If time, disassemble your SMTB structure and put the parts back in the cabinet neatly.
HW:
Finish any calculations that were not completed in class today.
Quiz on Simple Machines on FRIDAY.
Be able to draw and label a representation of a simple machine and perform calculations to determine IMA, AMA, and Efficiency of a simple machine. You will be able to use the formula sheet found in Important Files.
Review the two presentations we discussed about simple machines(all 6 types) and Thread Notes.
ACTIVITY:
Watch Bill Nye and Mechanical Advantage video then answer the following questions in your notebook:
How much mechanical advantage(MA) did they get from the pulley?
How were they able to achieve this much MA?
Review Lever, Wheel & Axle, and Pulley, and Inclined Plane, Wedge, Screw and Thread Notes presentations, then complete practice questions 10-24 in Activity 1.1.2 practice problems.
