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.

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
