Grade 8 brat pack clarification

Dear grade 8's

Some puplis have asked clarification on the brat pack work to study. It seems I have gone and given fancy names to some things you have done but to avoid confusion here it is in plain English;

The work covered relates only to the bridge building competition.


- Stress and Strain
Compression, tension, bending, transference, dissipation
http://www.technologystudent.com/forcmom/force1.htm

- Properties of materials
Of the wood and glue used in the competition.

- Conventional an composite materials
Joints as well as the wood and glue used in the competition.

Hope that helps.

Marius Buys

i) Intervention in unethical and ecological and irresponsible corporate drive for profit is needed.
j) Create value whilst reducing the carbon footprint.

Levers

1) There are 3 classes of levers: 1st, 2nd and 3rd class.

2) To determine the class we ask; "What is in the middle?"

We use the word "please" to help us to remeber the order of the classes.

P (pivot) 1st class
L (lever) 2nd class
E (effort) 3rd class
a
s
e

3) Terminology:
Lever (a long bar or something that acts as a bar with a load, pivot and effort acting on it)

Effort/Force (The energy we apply either by hand or machine.)
Pivot / Fulcrum (The point on the lever where there is rotation.)
Load (A weight that needs to be moved.)

4) The purpose of levers:
a) To apply a force at a distance.
b) To increase the result of the applied effort.
c) To change/affect the direction of an applied force.

5) In a 1st class lever; the closer the pivot is to the load, or the further the effort is applied from the pivot, the stronger that applied force will be.

6) Examples:
Class 1
A worker using a crowbar to lift a heavy rock from the ground.
Effort = Worker presses down on the far end of the bar.
Pivot = Small rock close to the large rock.
Load = The force that is amplified lifts the large rock out of the ground.

Class 2
A person using a door handle to open the door latch.
Effort = The hand turning the handle
Load = The unseen force being applied between the axle and the hand.
Pivot = The axle in the door handle.

Class 3
Broom
A person using a broom to sweep.
Pivot = The person using his top hand as a pivot.
Effort = The person using the hand in the middle of the broom to move the broom.
Load = The increased brushing power and distance of the broom at the cleaning end.
