1. Iron Man: Iron Man’s Suit

2. 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.

3. 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

4. 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

5. Gold Titanium Alloy How much would the Iron Man suit weigh?
It is estimated that the suit would weigh around 90 lbs.

6. 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.

7. 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).

8. 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
