What is fundamental period of a building?
The fundamental building period is simply the inverse of the building frequency at the lowest harmonic - easy right? Basically, every system has a set of frequencies in which it "wants" to vibrate when set in motion by some sort of disturbance (in building design, typically a seismic or wind event) based on the system's mass and stiffness characteristics. The shortest frequency is known as the natural frequency. The inverse of frequency is the period of the system, and more specifically, the inverse of the natural frequency is the fundamental period.
What is the design life period of a road?
It is a period considered appropriate to the function of the road. An arbitrary design period (say 25 years) needs to be chosen to enable the design of the road pavement to be developed. The determination of the total traffic the road will experience is a function of the design life chosen, and an estimate of the steady traffic growth expected over that period (say 2%). The resulting Design Traffic calculation is then used to determine what thickness the pavement should be to handle the stresses exerted on it from road vehicles over 25 years. It is accepted that after 25 years the pavement will likely need some sort of rehabilitation or construction, and the design process starts over again.

What is the Necessity of irrigation?
Throughout the crop period adequate quantities of water is required near the root zone of the plants for their growth. At times during the crop period the rainfall may not be adequate to fulfill the water requirement. The intensity of rainfall is practically uncertain and beyond the control of human power and it may not be well distributed throughout the crop season or the culturable area. So, irrigation becomes absolutely necessary to fulfill the water requirement of crops. The following are the factors which govern the necessity of irrigation, (a)Insufficient Rainfall: When the seasonal rainfall is less than the minimum requirement for the satisfactory growth of crops, the irrigation system is essential. (b)Uneven Distribution of Rainfall: When the rainfall is not evenly distributed during the crop period or throughoutthereculture able area the irrigation is extremely necessary. (c)Improvement of Perennial Crops: Some crops like sugarcane, cotton, etc require water throughout the major part of the year. But the rainfall may fulfill the water requirement in rainy season only. So for the remaining part of the year, irrigation becomes necessary. (d)Development of Agriculture in Desert Area: In desert area where the rainfall is very scanty, irrigation is required for the development of agriculture.
