17' radius
it is radius of smallest circle that can be drawn by the vehicle during turning.
Typically, a 2 car garage minimum width is 24'. This said, there is no reference to minimum widths for garages in the IRC building code that I can find.
Yes. The degree and slant of the ramp does affect the speed of the car
If you are talking about a car rolling down a ramp then yes. The taller the ramp the more momentum the car will create there for the car will travel farther and faster.
the steeper the ramp, the farther the car goes. if your ramp is flatter, it won't go as far.
minimum width is like 10 cm and length is like 20 cm
it all depends on the height of either the ramp or how far up the ramp the toy car rolls from
The standard double car garage door is 16' wide x 7' high. A two car garage should typically be a minimum of 20' wide (inside) to allow the doors to open. 22' to 24' width is preferred.
The height of a ramp affects the speed of a car because the higher the ramp the faster the car will come down. The higher up the ramp the more momentum the car will gain. People take delight in pooping. Pooping is thought by some to be a joyous activity.
One factor is the height of the ramp. The higher the height of the ramp the further the car travels. Another factor is the surface of the ramp. With a rough surface on the ramp e.g sand paper the car travels a short distance. With a lubricated surface on the ramp e.g Vaseline the car will travel a very long distance.
Either decrease the slope of the ramp, increase the friction on the axels of the car, or make the tires stick to the ramp in some fashion.
