Danny Rand hit Luke Cage with the Iron Fist sending him through two buildings.
We will use Luke Cage’s durability to calculate the power of the Iron Fist.
LUKE CAGE’S DURABILITY
In
Hero For Hire (1972) #1, we find out that Luke Cage has titanium steel skin from an accidental research experiment. We will use this statement to calculate the power of the Iron Fist.
NUMBER CRUNCHING
Since Luke Cage has titanium steel skin, we can compare the Young’s Modulus of both metals. To note, the Young’s Modulus is a measure of a material’s elasticity. In this case, titanium has a value of 106 GPa while steel has a value of 20*10
10 Pa. Hence, steel has the higher Young’s Modulus. Since we do not know their composite densities, we will use the value of steel to estimate Luke Cage’s durability in N/m
2.
Luke Cage’s durability = (20*10
10 Pa) = 20*10
10 Pa N/m
2.
Then, we calculate the force necessary to move Luke Cage.
Iron Fist’s force = (20*10
10 N/m
2)/(1.98 m)
2 = 51015202530.4 N.
Let’s calculate the power of the Iron Fist. We can estimate that Luke Cage went through two buildings 100 meters apart. According to
Destructive Capacity and Durability, it takes 10 tons of TNT to destroy a building. Since Luke Cage toppled the second building, we are adding 4.2*10
10 J.
Power of the Iron Fist = ((51015202530.4 N)(100 m) + (4.2*10
10 J)/(1 s) = 5.1435203*10
12 W.
SUPER STRENGTH
Hitting Luke Cage with the full force of the Iron Fist, Danny had to generate the power of a nuke. Indeed, he punched Power Man with 5.1435203*10
12 W of power.
Iron Fist generated 51015202530.4 N. In order to send Luke Cage flying through two buildings, Iron Fist had to generate a City Level of Super Strength.
