Q2 Sustainability is the concept of a lasting forward-looking development of all economic, ecological and social aspects of human existence. These three pillars of sustainability are interdependent and require a balanced coordination.

According to the World Intellectual Property Organization (WIPO), Intellectual property (IP) refers to creations of the mind, such as inventions; literary and artistic works; designs; symbols, names and images used in commerce. The IP is very important for the construction industry. This is because a lot of technical innovations occur in an engineering company and protecting their knowledge of IP is necessary.    (i)  Identify the protected rights under the IP law for the construction industry. (ii)  Discover the scope of protection of IP rights identified in (i).

(3.3) What are some of the common sources of indoor noise pollution, and how can noise levels be assessed and controlled in buildings? Note that this question is asking for two aspects, one is noise assessment and the other one is noise control.

Tribology optimizes bearing performance through surface engineering (finishes, coatings), lubrication strategies (types, systems), and wear mitigation (mechanisms, materials). Monitoring, failure analysis, and R&D further enhance reliability and efficiency in rotating machinery.

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. Bearing life is determined by load, temperature, maintenance, lubrication, material defects, contamination, handling, installation and other factors. What strategies are you going to make to lessen the effects of the mentioned factors?
