A Zygna game on facebook. You See cars and click the people then you drag them to the entrance. also you hire a ticket person that can be any of your friends 'even if they don't have one'. you look for a roller coaster and drag it to the front of the park and 2 people ride it at a time once
To save a roller coaster design simply select your roller coaster with your cusor and open the detials icon located to the right of the roller coaster cars design, now click the save ride icon and it will be saved. But make sure you name the ride before doing this other wise it may be saved as somthing you dont want. To delete the roller coaster go into the rct3 folder you created when you installed the game open the folder and go on coasters and simply delete the roller coaster you dont want. This is a great game, have fun playing it.
That will depend on which part of the roller coaster you're talking about. The moving parts (the cars and the driving mechanisms etc) will be designed by a mechanical engineer. The structure of the roller coaster itself (the towers and trackway and the foundations on which it stands) will be designed by a civil engineer.
When the roller coaster starts to stop your body wants to keep moving, that is inertia.
