Welcome to the new COTI server. We've moved the Citizens to a new server. Please let us know in the COTI Website issue forum if you find any problems.
We, the systems administration staff, apologize for this unexpected outage of the boards. We have resolved the root cause of the problem and there should be no further disruptions.
An interesting add here would be a block and tackle system at the top to give normal people a chance of lifting someone up in that harness. Doesn't have to be super elaborate, but you'll need more than just a pulley. In the end it can just be an eyelet mounted to the roof, then the pulley system can be hung in an emergency, stored in a box nearby vs "DOH! Clonked my head on that @&#$^@ pulley thing again!". Who doesn't love lose, swinging masses in a starship.
large amounts of mass, when moving even in zero G, are still large amounts of mass. 1 ton machine going 1 meter/second is still going to crush you if you get between it and the wall.
The Physics of the Impact
To understand why this is dangerous, we have to look at two primary concepts: Momentum and Kinetic Energy.
Momentum ($p = mv$): A 1,000 kg block moving at 1 m/s has a momentum of $1,000 \text{ kg}\cdot\text{m/s}$. For context, that is roughly the same momentum as a 100 kg (220 lb) linebacker sprinting at you at 10 m/s (22 mph).
Inertia: Newton’s First Law states that an object in motion stays in motion. Without gravity to create friction or weight to "hold it down," there is nothing to stop that 1-ton block except for you and the wall.
The "Crush" Scenario
If you are caught between the block and a solid wall, the block won't just bounce off you.
Compression: As the block hits you, it will attempt to continue moving at 1 m/s. Since the wall won't move, your body becomes the "crumple zone."
Force Application: To stop a 1,000 kg mass in a fraction of a second (the time it takes to compress a human body), the wall and the block would exert several thousand Newtons of force on your skeleton and organs.
Result: Because the block is so massive compared to you, it will hardly slow down as it passes through the space you are occupying. It would essentially treat you like a tube of toothpaste being squeezed against a table
