π Chapter 3 of the book covers introduction to engineering design and its additional considerations.
π Sustainability is an essential aspect of engineering design, aiming to meet present needs without compromising the ability of future generations to meet their own needs.
π§ Engineers contribute to both the private and public sectors, designing goods and services for a high standard of living and supporting various missions and needs.
Engineers must consider environmental, social, ethical, technical, and economical factors when planning for the future.
Integration of sustainability in engineering curricula is supported by organizations such as EASEEASME and IEEE.
Civil engineers play an important role in addressing climate change and sustainability issues.
The world's current economic development is not sustainable, with increasing resource consumption and population growth.
The engineering community should take a leading role in sustainable development but has not yet fully embraced the responsibility.
Civil engineers often deliver conventional design that maintains the status quo, while opportunities for innovation are explored by others.
π’ The video discusses the concept and importance of green buildings and the LEED rating system.
π The formation of the sustainability ad hoc committee and the global earth observation system of systems (GEOSS) are highlighted as efforts to promote sustainable development.
π‘ Key sustainability methods and tools such as life cycle analysis and environmental impact analysis are discussed.
π Sustainable development indicators and the USGBC LEED rating system are internationally recognized for improving building performance.
πΌ Engineering design decisions should consider product cost, affordability, and profitability for the company.
π¨ Material selection is crucial and should take into account properties such as density, strength, flexibility, durability, and more.
π Material properties and specifications are important to ensure meeting standards.
β‘ Different materials have varying electrical resistivity and conductivity.
π Material density and elasticity affect its behavior when stretched or compressed.
π Shear modulus determines a material's resistance to twisting or shearing.
πͺ Tensile strength is the maximum load a material can carry without failure.
π© Compressive strength is the maximum load a material can carry without failure.
π Modulus of toughness indicates the ability of a material to handle overloading before fracturing.
π Fluid viscosity determines its resistance to flow.
π§ Water has a higher vapor pressure than glycerin.
π Bulk modulus measures fluid compressibility.
