Iron Man:Iron Man’s Suit

Gold Titanium Alloy

What is an alloy?A metal made by combining two or more

metallic elements, esp. to give greater strength or resistance to corrosion.

Gold Titanium Alloy

• Is gold titanium alloy real?– a 90% gold / 10% titanium mix produces a hard

and strong but brittle alloy– Gold-titanium alloys are used in dentistry

Gold Titanium Alloy• Could the suit be bulletproof?– A material is brittle if, when subjected to stress, it

breaks without significant deformation. – Brittle materials absorb relatively little energy

prior to fracture, even those of high strength.– Breaking is often accompanied by a snapping

sound.• Can metal be used as a bulletproof material?– ¼ inch thick iron or steel is an effective bulletproof

shield

Gold Titanium Alloy

• How much would the Iron Man suit weigh?– It is estimated that the suit would weigh around

90 lbs.

Extra Strength

• How does an exoskeleton increase a person’s strength?– sensors detect contractions of a human user's

muscles and use them to operate a series of valves, which in turn regulate the flow of high-pressure hydraulic fluid to the joints.

– how hydraulics increase force

Rocket Propulsion System

• How does Iron Man’s suit fly?– Newton’s Third Law of Motion: For every Action

there is an equal and opposite Reaction.– The fuel exhaust is forced out the hands and feet

(Action) causing Iron Man to be propelled forward (Reaction).

– how a rocket works

Rocket Propulsion System

• Can Iron Man’s suit make him fly?– Physics equation: • (mass of Iron Man)x(velocity of Iron Man) = (Mass of

propellant)x(velocity of propellant)• (300 lb)x(500 mph) = (mass of propellent)x(5000 mph)• mass of propellent = 30 lbs

• Can the suit fly 500 mph?– 30 lbs of propellant must be used every minute to

maintain his speed while flying
