  • It varies by army, so this won’t be exact.

    A platoon has around 30 people in it. It has around 20 privates, about 7 non commissioned officers and one commissioned officer. Say 3 lance(junior) corporals, 3 corporals and a sergeant. In overall command is a commissioned officer.

    When you join the army you typically go in as non commissioned as a private or commissioned as a leuitenant.

    Officers are trained to lead people from the start. The lieutenant may have 1-2 years experience and the sergeant may have 16 years experience.

    The next level up is a captain who commands say 3-5 platoons. At the start of saving private Ryan, Tom Hanks character was a captain in command of around 100 soldiers.

    I think around 5 companies make a battalion. And that’s just soldiers.

    You can also make a unit out of soldiers, engineers, artillery, transport and some other specialists like medical and cooks.

    I believe a brigadier general would command a unit around this size.

    To get there I would expect he worked his way up the rank, working at each level for around 2-3 years.

    He would have been in the army around 15-20 years, but some people could get promoted faster.



  • I’m not a switch expert but can think of a reason why it might do this.

    The system might show it’s battery level to you as 100% to 0% when it might actually be draining from 100% to 5%. That last 5% might be used as a sort of internal Uninterruptible Power System .

    When the system boots up it might be doing some things where a power failure could have severe consequences like bricking the unit if the plug was pulled out and there was no battery.

    The system might use some swap space like storage or have some key variables kept in RAM which needs to be written out to non-volatile memory before the chips are powered down.

    For example let’s say it hibernates and it doesn’t or incorrectly writes the wrong instructions pointer address When the system poweres up, it might try and execute game data instead of instructions and not recover.

    Nintendo wouldn’t want to handle heaps of complaints of bricked systems due to exceptional circumstances like a power outage if it let the switch play off mains alone.

    That’s my theory, I could be wrong and I’m sorry it’s frustrating you.



  • I feel communities can be put in 3 categories.

    1. Everything here is safe for work

    2. Things here are not safe for work, e.g. adult communities. There might be a bit of safe for work, but anyone browsing it knows what to expect

    3. The third is a combination. It might have a community rule that anything NSFW is tagged as such. With my browsing setup I have to click on NSFW posts to reveal them.

    I’d have a look around for an art sharing community. I think theres one on world and they might allow NSFW content and people would be more likely to give you relevant feedback.






  • That could happen with propellors that have Constant Speet Units. (Propellor pitch is able to be changed) The act is called ‘feathering’ . This can happen on multi engine aircraft and reduce the drag of the side with the failed engine. Cheaper propellors are fixed pitch and no means exist to change them. (I believe some propellor are able to have their pitch changed by a maintainer on the ground so the aircraft can be optimized for climbing, cruising or a combination of both)

    ‘Reverse Thrust’ is also possible in so e Other aircraft. the blade reverses to the point where it pushes the wrong way so the engines assist breaking* after landing. * Typo, but I’m leaving it in =)


  • Not exactly a scientist, and I agree with the other long answer about blades disrupting each other, so I’m replying to see if I can help you visualize/understand some of the forces at play.

    My source is a Tom Clancy book about a sub war.

    Typically the subs are stealthy, however if I remember correctly, I’d they decided to gun the engines (think something like 105% on the reactor), they could spin the blades really fast.

    But compressing the water as the blade spins makes some of it high pressure and the other side of the blade low pressure.

    This would reduce the pressure low enough that the water would become a gas and in doing so, make a lot of noise and was called cavitation.

    When the sub commander did this, it did mean the ship could go very fast, but was noisy as hell and anyone near would know they were around, but if someone shot a torpedo at you and you had to get out of range…

    Before readying the other reply I thought something like this might have happened and disrupted the smooth laminar airflow.

    I know aircraft have over speed and under speed warnings for propellors too, but I thought that was more to do with not breaking them than 'grabbing the air ’ efficiently. Supersonic propellor tips aren’t a good idea.
