What type of force tends to pull materials apart?

• Tensile force

• Compression force

• Frictional force

• Shear force

Which force tends to push materials together?

• Force of tension

• Force of repulsion

• Force of compression

• Force of attraction

What type of force occurs when two parts of a material slide past each other in opposite directions?

• Compression force

• Shear force

• Tension force

• Friction force

Which force is responsible for holding objects on the surface of the Earth?

Give an example of a natural structure.

• Rock

• Building

• Cloud

• Tree

Provide an example of a manmade structure.

• Statue of Liberty

• Taj Mahal

• Big Ben

• Eiffel Tower

What are frame structures primarily made of?

• steel or reinforced concrete

• wood or glass

• brick or stone

• aluminum or plastic

What are shell structures known for?

• Known for their square shape and inefficient use of materials

• Limited in size and unable to support heavy loads

• Efficient use of materials and deriving strength from their curved shape

• Fragile construction and lack of stability

Differentiate between manufactured and human-made structures.

• Manufactured structures are temporary, while human-made structures are permanent.

• Manufactured structures are made of organic materials, while human-made structures are made of inorganic materials.

• Manufactured structures are produced in a factory or by machinery, while human-made structures are built by people.

• Manufactured structures are built by robots, while human-made structures are built by animals.

What are the advantages of using frame structures in construction?

• Flexibility in design, ease of construction, cost-effectiveness, ability to support heavy loads

• Difficult construction process

• Limited design possibilities

• High cost
