Why doesn't it go backward?

Lighter mechs would be knocked further back, a 20-ton mech about 4-5 meters if jumping straight up. Heavier mechs less so. In all cases it would b dependent on relative velocity.

And would they shake? Without solid ground the gyros are not dampening vibrations resultant from the collision. There would just be a single jarring impact.

Be to much for PGI to code in.....would be funny if the mech was knocked sideways and came down just wrong and broke a leg joint or something as well. or fell down upon impact, with a pilot skill tree taht helps reduce that effect...but that would require thisgame to have depth, point and immersion.

[Bishop Steiner]

I'd love it, but doubt PGI can do it... at least not with their resources, and priorities. Oversized Mechs are job 1!

[Robomomo2000]

Well, The ACs are not just cannons like they are portrayed in MWO for the IS. Instead they function much like machineguns (auto cannons) much like the Clans, but it would be twenty single damage shots. Ultras and Rotary ACs shoot faster hence the ability to shot during cool down. That's why a function like that is not implemented; the shots have about the impact of a missile.

As LordKnightFandragon said, it would be a lot to code, and PGI has a lot more important stuff on their plate right now.

lets assume a 20 ton locust got hit.
You can calculate the mass of an AC20 round by taking 1 ton of ammo and dividing it by the number of rounds.

Ac20 rounds are 5 per ton, meaning each is 0.20 tons each. (per lore, MWO upped the ammo)

so its like a 200 pound man getting hit by a 2 pound brick. would hurt, but that brick has gotta be going pretty fast if it wants to change a person's velocity, even in the air.

[ThrashInc]

Without doing the math, the Locust would absorb ~115,000kg m/s worth of energy just from the weight of the shell. I'll let you consider what would happen to a 20t object that would be considerably top heavy with zero forward momentum.

hell yeah

because of how mech armor functions, a lot of energy would be transferred into the armor that flakes and sheers off.

[HellJumper]

Becuase they cannot do it...

we have no knockdowns in game..so nothing like this will happen as well

[GumbyC2C]

According to TT rules, if you take 20+ points of damage in the fire phase you have to make a piloting check at a +1 modifier for every 20 points. So yes, it should impact even big mechs, but it doesn't. (I know, TT doesn't apply to a sim but TT did have a rule for this)

Assuming the AC20 shell weighs 142 kg (it couldn't because some of it must be propellant, so the actual projectile must weigh less, but to err on the maximum possible), since it flies at 650 meters/sec, it has a momentum of 92300 kg m/s.

A 20 ton mech, massing 20,000 kg, assuming a perfectly elastic collision (which is also ain't, since some of the energy goes towards deforming the armor), would get shoved back at about 4.6 meters/sec. Which is about 16 kph.

Not that big a change in speed.

[ThrashInc]

Which ton did you use, should be like 180kg.

[Anjian]

Can't code this level of realism.

By the way, do you notice that if an aircraft is hit by a large projectile, it doesn't jerk back. It continues to go forward, albeit in pieces.

Assuming metric ton. And using MWO's 7 shots of AC20 per ton.

Pretty sure a single AC20 shell wouldn't knock over even a Locust. Don't know physics though. Planes getting hit by flak don't get deflected by the flak from watching movies (or not enough for anyone but the most pedantic person to really give a hoot).

should be 5 shots in lore. 0.2 tons per shell (assuming you use a single shot and not multishot, which would render this argument even more useless) MWO had to up the ammo per ton because they changed armor values.

they would shake, also I think flak works by using shrapnel to shred a plane and try to kill the crew not via blast.

[Anjian]

What happens when a solid shot (HEAT, APFDS, APCR or AP) hits a target?

It would break through the wall, The inner wall splinters, sends fragments in all directions inwards (spalling).

The projectile itself would break up, sending fragments inside the inner compartment.

An inner explosion inside the mech body would send the head and the cockpit, popping out of the body. Its possible the poor pilot would smash through the cockpit glass on his or her way out.

[SmoothCriminal]

Imagine the processing that would have to be implemented here. Projectile size, velocity, impact area, angle of impact, target momentum, target size... all would need to be calculated on the fly. If you want to set aside a portion of your life to do this then go for it!

[Anjian]

A shotgun blast, like an LBX 20 should be able to knock a mech down, but once its down the mech is already combat ineffective as it would be very difficult to bring it up.

Also realistically, if mechs fought in the bog, not only would some sink in it, but the lasers and the missiles would set it on fire, while trees would be cut down by the ballistics.

[Lynx7725]

If that happens, then I suppose getting hit by LRMs while jumpjetting would spin the mech round and round, upside down?

I might pay money to watch that. Might.
