The number of piles used and length of span depend on the specific project requirements.

• The number of piles used will depend on the load capacity required for the structure.

• The length of span will depend on the distance between the supports and the load capacity required.

• Factors such as soil conditions, environmental factors, and budget will also impact the number of piles and length of span.

• For example, a bridge spanning a river may require more piles and a longer span than ...read more

The question is about types of beams and advantages, and the height of a cycle tire.

• Types of beams include cantilever, simply supported, fixed, and continuous beams.

• Advantages of beams include their ability to support weight and distribute loads evenly.

• The height of a cycle tire varies depending on the type of bike and the size of the tire.

• For example, a road bike tire may have a height of 23mm, while a mountain bike tire may have a height of 2.5 inches.
