Different Structures
What are the three types of structures?
Mass structure, Shell structure and Frame structure
What is complementary force?
Two forces acting on something at the same time.
What is weight?
Weight is the measure of the amount of gravity in an object.
What is a structure?
Something that has a shape and size with a function.
Which force is a complementary force?
1. bending 2. torsion 3. shear 4. tension
bending
What static load?
Effect of gravity on an object
Do you think structures are important to our daily lives? Explain.
No exact answer. Your opinion.
Compare and contrast internal and external force.
Internal forces are forces that come from the object's own body and external forces are forces that come from the outside.
The point around which a structure's mass is equally balanced in all directions.
Centre OF Gravity
Give an example of a natural and manufactured structure. Compare and contrast.
No exact answer.
List all the internal forces.
Tension,torsion,shear,compression and bending
Units
Compare and contrast the three different types of structures.
No exact answer.
For example:
Mass: pilling up materials that are similar
Shell: The inside is middle. It can make a good container.
Frame: Skeleton. Usually, on the outside to protect objects on the inside.
List out one of the external force that appears in your daily life.
