The concept that 'organizations on the other hand depend on people' means:
This emphasizes the fundamental dependence: without people, organizations would disappear. Despite technology and automation, people remain essential - they create, operate, innovate, and sustain organizations. The relationship is one of mutual dependence.
Stress is defined as $\frac{\text{Force}}{\text{Area}}$.
- Force (Weight) $\propto \text{Volume} \propto L^3$
- Area $\propto L^2$
- $\text{Stress} \propto \frac{L^3}{L^2} \propto L$
- Since $L$ increases by factor $9$, stress increases by factor $9$.
A synchronous generator with inertia constant $H = 5\,\text{MJ/MVA}$ is rated at $100\,\text{MVA}$. The angular momentum coefficient $M = GH/(\pi f_s)$ used in the swing equation (at $50\,\text{Hz}$) is approximately:
Stored kinetic energy $= H\times S_{rated} = 5\times100 = 500\,\text{MJ}$. Swing equation inertia: $M = \frac{GH}{\pi f_s} = \frac{100\times5}{\pi\times50} = \frac{500}{157.08} \approx 3.18\,\text{MJ·s/rad}$.
