How the Leaning Tower of Pisa Was Saved: Crash Course Engineering #40

The video explores the structural challenges faced by the Leaning Tower of Pisa and the Civic Tower in Pavia, highlighting the importance of geotechnical and seismic engineering. It explains how foundations connect structures to the ground, the role of soil mechanics, and the concept of bearing capacity. The video also covers the stabilization efforts for the Pisa Tower and the role of seismic engineering in earthquake-prone areas, emphasizing the need for strong foundations and soil analysis to ensure structural stability.

What was the main issue that caused the Leaning Tower of Pisa to tilt?

• The tower was built in a windy area.

• The tower was built on a solid rock foundation.

• The tower was constructed with uneven materials.

• The tower's design was too heavy for its foundation.

What is the primary focus of geotechnical engineering?

• Building bridges

• Investigating soil and rock for construction

• Creating earthquake-resistant structures

• Designing skyscrapers

Which property of soil is crucial for determining its ability to support structures?

• Color

• Shear strength

• Temperature

• Moisture content

What contributes to the shear strength of soil?

• The size and shape of soil grains
