I always wondered, why the light mechs could run circles around my heavies and assaults.

It's an illusion! They can't !

Because .......

If you meassure the running radius of a light mech (for example the commando) ist about 25 meters. A circle can be run within 50 m.

Lets calculate the centrifugal force:

v = velocity of mech = 130 km/h = 36.11 m/s
r = radius of circle = 25 m
m = mass of mech = 25 tons

Centrifugal force F(c) = m* v^2 / r = 25000 kg * (36,11m/s)^2 / 25 m = 1304932 kgm/s^2 = 1304932 N

Now lets have a look at another force:

Wight F(w) = 25000kg * 9.81 m/s^2 = 245250 N

To calculate the nessessary tilting of the mech while running circles:
tan (alpha) =F(c) / F(w) = 1304932N / 245250 N = 5.32
alpha = arctan (5.32) = 79.4 degree

The mech has to turn his axis in a angle of 79° away from the vertical axis to the centre to make shure it can run a 50m circle at 130 km/h. That's impossible.

While doing this the resulting accelleration a® that takes effect on the Pilot is 5,32g.

Lets have a look at the following table, which shows the effect of exposure to acceleration for more than a few seconds because the Blood is forced to flow into the feet and the head gets under supplied.

1-2g no problems
2-3g field of viision starts to get smaler
3-4g tunnel vision
4-5g memory gaps appearing
5-6g unconsciousness

With modern anti-G-suits it's possible to stay OK at 9 g for a short time, but as we know from the Battletech literature the pilots are often wearing only a cooling vest.

So while running the same circle for 20 seconds at 5.32g the Pilot schould get unconscious.
And that means death in a Battle!

How are you having trouble killing enemies who run in a circle around you?

HSR

working as intended

[bad arcade kitty]

fighter jet pilots regularly expose those accelerations and can briefly tolerate 10+g, people can tolerate 5g for a rather long time

>Early experiments showed that untrained humans were able to tolerate a range of accelerations depending on the time of exposure. This ranged from as much as 20 g for less than 10 seconds, to 10 g for 1 minute, and 6 g for 10 minutes for both eyeballs in and out.

also the radius of cod is usually ~twice-thrice as more than 25m that you stated which severely diminishes the centrifugal force

[Queen of England]

If you really want to go all out, you should factor in MWO's really high gravity. I think its 32 m/s^2, so a little more than 3g.

Giant two legged war robots and physics dont really go together.
There is a reason they dont exist.

Its all just imaginary novelty value.

Dude...it's battletech. These robots would collapse on themselves. They could never function. It's not even close to realistic.

[Kiriesani]

Sure account for G forces.

My locust is obviously overpowered as it is.

Ask me... It's a dive of epic proportions. But that's Football.

In hindsight... I might have to keep this gif around. It makes an excellent simile to the reactions to the quirk announcement.

I have no problems with killing light ones. especially with my jagers.
I only wondered about their running style.

if I drive my Motorbike with 130km/h around a corner, it looks different (and the corner is wider than 50m)


@Bridesmaid
yes you are right. it depends on the direction of the force.
If the mechs are running like they do right now, the main force is in the horizontal axis. but
you have to add the bouncing of the cockpit so the pilot gets forces in every possible direction. Then Its likely that his neck will break.

In my (tilted) example the force mainly comes from the vertical axis,
in the graphic on the page you have cited the green line. And it says 5g for 3 seconds.

In both ways the pilot will have Problems, i think

Inb4 the "handegg" argument starts.

[White Bear 84]

You ought to calculate the weight based on the relative gravity of each planet. Im sure the G's in tourmaline would not be the same as the G's in HPG?

[MauttyKoray]

1. I believe OP was literally talking about the physics involved in the mechs in MWO, not a 'I can't kill them' or 'HSR broken' post. Legitimate maths here people.

2. Think of a mech like a very large human, not a car. The mech can lean, tilt, and dig its foot into the ground to push off hard and immediately change direction...or that's how it would be in lore.

Anyways, yeah its a little ridiculous. The skill system is extremely broken with the addition of quirks...bandages on bandages, covering the real problems.

[xDust]

I don't think light mechs are running full speed when circling for that length of time, and they aren't circling in that tight of a radius at that speed.
