I would hate to be the person in the front car!

This scene would be rated a 10 if it weren't for the fact that the wheels on the front car did not stay on the track, and the car ended up sort of hanging to one side and flipping around as the coaster hit the loops and turns. It needs a little work. Except for that, you did a great job on it!

The gears turn opposite direction because the driving motor connects the front gear to the back gear, rather than to the background or any other support. The other non-motor axle connects the rear gear to the background. Think of it this way: The shaft of the motor is connected to one gear, and the body of the motor is connected to the other gear. The shaft drives the gear in one direction, and the counter-torque that the body creates drives the other gear in opposite direction.

How about making a Robinson R44?

Seems to work a little better when air friction is turned off.

This isn't a Rail Gun. It operates sort of like a Coil Gun.

Regardless of the title, this scene does not explain how to build a gun.

What do you mean "sorry safe"?

Shoting? Did you mean "Shooting"?

Three phase ac power.

Cool effect!

The rod is infinitely long!

It's very accurate! Nice job!

I don't understand what this is about. Is this a game? If so, then how is it played? What keys are used, etc? Sorry, but this makes no sense.

Cool effect! Nicely done!

Sorry, but this makes no sense at all.

There are HUNDREDS of ragdolls on Algobox! I'm sure that you could find one that would work for your scene.

It shows.

Always has. I don't know why your view is different than mine unless it has something to do with the difference in browsers.

Nope. A Rail Gun works on a totally different principle. A Coil Gun uses a coil of copper wire that produces a pulsed magnetic field which propels the projectile. A Rail Gun uses two very long copper rails that the projectile slides along and gets accelerated continuously until it leaves the rail. Do the research so you can learn the difference and see how different the two types actually are.

Here are a couple of links for you:

This is actually a great idea for a car security system!

Excellent demo of a hydraulic system! My only comment about its operation is, the pilot operated check valve doesn't seem to work. first off, I assume that the rectangular sliding block with two springs is the check (or relief) valve. Am I correct? If so, it doesn't seem to move under any condition, even when the cylinder is at maximum extension.

Maybe your next scene could be a hydraulic system with a double acting cylinder!

Oh, and welcome to Algobox! I see that you registered in 2010, but this is your first uploaded scene.

Nice job!

The guns flip backwards off their supports when fired. They should be fixed to their supports to stabilize them.

I pressed the numbers in reverse order and it still worked!

This is an educational scene because I did not know that you can trigger a laser using more than one key at a time! I learned something new today. THANKS!

I agree with you Gent. Sometimes increasing the Sim Frequency helps with water and other objects leaking through walls. But of course you can't make the frequency too high because the lag will increase proportionately. Most physics simulation programs rely on really high-end computers for a true-to-life simulation, but, unfortunately, most people do not have really high-end computers.

@goof245 - I tried what you suggested, and yes, I can now see the pressure relief valve open when it should.

Poor little kitty!

Nice job. Even the cyclic and collective move like they should!

Just curious.... Are you a real helicopter pilot?

Interesting things happen when I place a few of those yellow projectiles near (and on top of) the gun when I fire it. They are all affected by the magnetic field, and go flying off in different directions. COOL!

Nice work on the scene.

EDIT: How does this work? The part that I don't understand is how the rectangles sequentially move along the gun barrel. Is it the code in one of the lasers that does that? Please explain. Thanks!

AHHhhhh.... the code in the hinges. Brilliant!

Hmmmm..... The code in all those hinges looks strangely familiar!

Interesting and fun scene!

Just curious.... Why do you make pictures of cell phones for your scenes? Do you sell them?

Godly stature? HUH?
