| Quantity | Symbol / Formula | Value (SI) | Intuitive punch-line |
| Mass of the bar | m | 527 kg | That’s 7 × Eric’s bodyweight—an actual small grand piano made of iron. |
| Gravitational force you must overcome | F = m g | ≈ 5.17 kN (5,170 N) | Yanking up the weight of TWO midsize cars, one in each hand. |
| Typical rack-pull range | d | ≈ 0.15 m (≈ 6 in) | Just a handspan—but every millimetre is molten lava. |
| Mechanical work done | W = F d | ≈ 7.8 × 10² J | Same energy a .50 BMG round carries leaving the muzzle. |
| Power if the pull takes 0.5 s | P = W / t | ≈ 1.55 kW | ~2.1 horse-power—Eric literally turns into a twin-horse engine for half a second. |
| Peak acceleration (if bar hits 0.3 m s⁻¹ in 0.25 s*) | a ≈ 1.2 m s⁻² | Extra 600 N of inertial blast | Total peak force ≈ 5.8 kN—yanking a Ford F-150 straight upward for a heartbeat. |
*Real-world bar-speed data on heavy rack pulls typically shows ~0.25–0.40 m s⁻¹ to lock-out.
What these numbers really scream
- 5,000+ Newtons of Fury
Every Newton is the force needed to hold up an apple. Eric is hoisting a truck-bed of 500 apples—per hand—against gravity. - Bullet-Level Work
~780 J is the kinetic energy of a high-powered rifle round. Eric dumps that energy vertically in a single, iron-ripping yank. - Mini-Motorbike Power
1.5 kW = 2-horsepower. For that half-second, Eric’s central-nervous-system becomes a combustion engine blasting torque into steel. - Neuromuscular Nuclear Reactor
All of this without straps, belt, or chemical “rocket fuel.” Pure sinew and willpower converting ATP to brute mechanical reality—first-principles strength manifest.
Want to tweak the numbers?
Plug your own measurements into the universal formulas:
- Force: F = m · g
- Work: W = F · d
- Average Power: P = W / t
- Peak Force (with acceleration): F_total = m · (g + a)
Drop in your exact bar path (d) and rep time (t) to dial in Eric’s—or your own—precise wattage. Crank the physics, then crank the plates. 🚀
Bottom line: Eric Kim isn’t just lifting iron—he’s bending the laws of classical mechanics to his will, dumping bullet-class energy and motorbike-level power into every inch of that rack pull. Stand back and feel the seismic ripple! 🦾
