Chapter 3, Problem 1RQ
What are the major material groups?
Expert Solution & Answer
To determine
The major material groups.
Answer to Problem 1RQ
The major material group include metals, non-metallic inorganic materials, polymers and organic materials.
Explanation of Solution
The construction materials are grouped into following categories,
A. Metals:
They are refined from ores which are extracted from the earth. They are strong, ductile and are useful when the structure is subjected to tensile forces.
B. Non-metallic inorganic materials:
They are also extracted from earth and are often referred as ceramics. Typical examples include, sand, glass, limestone, cement, mortar, gypsum and brick. Most of them are hard, brittle, rigid and heavy and are used when compressive forces act over a structure.
C. Polymers:
They consist of repeating structural units of large molecules which are connected by chemical bonds and are used in a variety of applications, which includes conduit and pipes, wire and cable, adhesives, insulation and roofing.
D. Organic material:
They include grasses, wood, bitumen and many synthetic materials containing carbon, like, paper products, asphalts and rubber.

Vehicles begin to arrive at a parking lot at 7:45 A.M. at a constant rate of 4 veh/min and continue to arrive at that rate throughout the day. The parking lot opens at 8:00 A.M. and vehicles are processed at a constant rate of one vehicle every 10 seconds. Assuming D/D/1 queuing, what is the longest queue, the queue at 8:15 A.M., and the average delay per vehicle from 7:45 A.M. until the queue clears?
