Overview of transportation engineering

 Transportation is the activity which facilitates physical movement of people and goods from one place to another. Role of transportation    Transportation plays an important role in the prosperity of a country. It contributes in all realm of developments such as economical development, industrial development, social and cultural one. As much as we invest in transportation sector, we get much economic growth. Transport sector contributes to 6% of Indian GDP and the contribution is increasing continuously. A developed transport system turns a local market into national market. It increases the export import from the availability of raw material. It connects the rural market or distributor to the cities. It increases the productivity of different industries. It promotes the globalization. It improves the living condition of people. It influence the formation of urban societies. It exchanges the adoption of different culture. Modes of transportation There are mainly four mod...

Explain the condition, How the member goes under direct as well as bending stress.

Image
  When the member is subjected to an eccentric load, it goes under direct as well as bending stress. Explanation -   We consider a member which is subjected to an eccentric load, P with eccentricity 'e'. Now, we introduce two load, along its axis, which are equal to P and parallel and opposite to each other. In the above figure, the additional two forces will not make any change in load pattern because they are equal, unlike, collinear and their resultant is zero. Now, we break out the above diagram into two parts - The downward force P acting at the centroid of section will produce direct stress. (see the left figure) And the remaining two forces (P || P) will form a couple and moment of this couple will produce the bending stress. Thus, in the case of eccentric loading, the member will sustain both stresses the direct and the bending. Thank you.

Introduction of steel (types, mechanical properties, stress-strain curve, advantages and disadvantages).

Image
Steel - It is an important structural material which is broadly used to construct structural member. It is an alloy of pure iron, carbon, chromium, Nickel and some other elements. In the steel, corrosion exists. Stainless steel - It is the alloy of pure iron and chromium. 11% chromium content are present. It is a corrosion resistance material. Types of steel - Effect of carbon content on steel characteristics- If carbon content in steel increases, the strength, hardness and brittleness will increase. If carbon content in steel decreases, the strength of steel will decrease and ductility of the steel will increase. Steel becomes soft. Stress-strain curve of Mild steel - OAB - It represents a straight line curve. The strain produced is proportional to the stress producing it. i.e, it obeys Hooke's law. A - represents the limit of proportionality - the stress beyond which linear variation ceases. B - represents the elastic limit - the maximum stress up to which a specimen regains its...

Planning of building - Orientation

Image
 Planning of a building includes various principles such as aspect, prospect, orientation, privacy, circulation, grouping, roominess etc. Today we will talk about the principle of orientation. so, now let's start.   Orientation means arrangement of rooms with respect to the north direction. In a plan of building, we can place the all types of rooms in various way. Some way may be effective or some way may be ineffective or unattractive. Generally, people make the plan themselves for their proposed residential building and in this connection they get quite confused in placement of rooms like kitchen, bathroom, living room, bedrooms, study room, store room etc. So, today I will give you a idea of how to place different types of room to get a pleasant feeling.  According to civil engineering, the plan should be oriented with respect to the north in such a way that kitchen lies towards east and north - east, bedrooms are towards south to southwest and maximum hall windows sh...

Analysis of perfect frame (Truss)

Image
  Definition of frame A structure made up of several bars riveted or welded together is known as frame. Types of frame There are two types of frame - Perfect frame and  Imperfect frame Perfect frame - A perfect frame is the which follows the equation n = 2j - 3. where, n = number of members and  j = number of joints In this type of frame, the number of members are just sufficient to keep the frame in equilibrium under an external load. There is no extra member is present in a perfect frame. Imperfect frame - An imperfect frame is one which does not follow the n = 2j - 3 equation. If the number of members in a frame are less than ( 2j - 3 ) then the frame is known as deficient frame. If the number of members in a frame are more than ( 2j -3 ) then the frame is called redundant frame. Assumptions made in analysis of frame The following assumptions are made in finding out the forces in a frame -  The frame is a perfect frame.  The frame carries load at the joints....
