Understanding Rocket Design and Safety

What is a factor of safety in engineering design?

• A measure of the weight of a structure

• A measure of the extra load a structure can handle beyond its expected load

• A measure of the speed of a machine

• A measure of the cost of materials

Why do engineers use a factor of safety?

• To reduce the cost of materials

• Because they are not sure what might happen in the field

• To increase the speed of production

• To make the structure look better

What is the typical factor of safety used in rocket design?

• 1.1 to 1.2 times the expected load

• 5 to 6 times the expected load

• 10 to 12 times the expected load

• 20 to 25 times the expected load

What is the main reason for keeping the factor of safety low in rockets?

• To reduce the cost

• To reduce the weight

• To increase the speed

• To increase the size

What is the purpose of the coolant in the machining process?

• To heat the material

• To capture chips and debris

• To paint the material

• To polish the material

What is the role of the craftsmen in the rocket factory?

• To design new rockets

• To ensure the quality of machined parts

• To operate the CNC machines

• To transport materials

What is an isogrid?

• A type of fuel used in rockets

• A structural pattern used in rocket design

• A type of engine

• A type of software

What is the main material used in the machining process described?

• Plastic

• Wood

• Metal

• Glass

What happens to the metal chips after machining?

• They are thrown away

• They are recycled and sent back to the supplier

• They are used as fuel

• They are melted and reused immediately

What is the main challenge when machining long parts?

• Keeping the part cool

• Aligning the part correctly

• Painting the part

• Transporting the part
