Structural Strength and Stability Quiz

What is the centre of gravity?

• The point at which the mass of an object is concentrated

• The point at which an object is perfectly balanced

• The point at which an object is most stable

• The point at which an object is most likely to fall over

What makes a structure stable?

• The materials the structure is made from

• The distribution of mass in the structure

• The height of the structure

• The width of the structure

How can you find the centre of gravity of an object?

• By picking it up and observing its motion

• By measuring its height and width

• By calculating the mass of the object

• By observing its support base

What happens if the centre of gravity is located outside a structure's support base?

• The structure becomes more stable

• The structure becomes less stable

• The structure remains stable

• The structure collapses

What is one way to make a structure more stable?

• Widening its base

• Increasing its height

• Reducing its mass

• Narrowing its top

Why are tapered structures more stable?

• They have a higher centre of gravity

• They have a narrower base

• They have a lower centre of gravity

• They have a wider top

What can football players do to increase their stability?

• Spread their feet apart

• Crouch down

• Jump in the air

• Stand up straight

What is the purpose of designing a stable chair?

• To prevent injuries

• To make it more comfortable

• To make it look aesthetically pleasing

• To save space

How can the stability of a building be improved without decreasing its height?

• Increasing the width of the base

• Adding more floors

• Using lighter materials

• Removing windows

How do giraffes prevent themselves from tipping over?

• By bending their knees when drinking

• By keeping their necks straight

• By crouching down

• By spreading their legs apart
