BINGO Unit 4 Review!
The force of gravity exerted on an object. It changes if you are on the moon.
A type of structure in which a skeleton of materials supports the weight of the other parts. Ex. A chair
Kilogram • The primary standard for mass- the unit used to measure mass. How many newtons does 1 kg weight on Earth?
A process that uses a different material to join two materials together by melting?
This ensures that a structure has extra strength to support more load than normal
An object with a definite size and shape, which fulfills a specific purpose or function. The parts have a specific arrangement that stays the same
An example of this is the motion of a bicycle wheel- the reason you can ride with no hands sometimes!
When two parts are pressed in opposite directions at the same time. Ex avalanche
The point at which all of the gravitational force of an object may be considered to act. It needs to be balanced in a stable structure
There are two types of these; solvent-based, which harden as they dry out, and thermosetting, which harden as they cool
A force on a structure that is not part of the structure itself. Ex. Wind, weight of people, collision
