How to get Civil Engineering Degree in Chhattisgarh:

-
Your Guide to get Civil Engineering Degree in Chhattisgarh Introduction Admission Related Guide for Students who want to Study Engineering To pursue a B.Tech in Civil Engineering in Chhattisgarh, you must first complete your 12th standard with Physics, Chemistry, and Mathematics. After that, you need to appear for the Chhattisgarh Pre-Engineering Test (CGPET) conducted by the Chhattisgarh Professional Examination Board (Vyapam). If you secure a good rank in the CGPET, especially under 2000, you have a high chance of getting admission to one of the three government engineering colleges in Chhattisgarh: GEC Raipur, GEC Bilaspur, or GEC Jagdalpur. You'll need to choose your preferred college during the counseling process after the CGPET results are declared. Regarding fees, government engineering colleges are relatively affordable. For general category students, the annual fee is around ₹22,000. However, students from reserved categories (SC, ST, OBC) can avail scholarships, reducing ...

Stress Strain Curve for Mild Steel

Image
 Stress Strain Curve for Mild Steel    OA is Proportionality limit • OB is Elastic limit but OB is Non linear • The slippage of the carbon atom within a molecular mass leads to drop down of stress marginally from C to C’ • C is upper yield point • C’ is lower yield point (also known as Yield Stress f y ) • For exp Fe-250 => f y =250N/mm 2 • C’D is constant stress region called Yield Plateau DE is Strain Hardening region, material starts offering resistance against deformation • EF is Necking region where drop down of stresses occur upto Failure point • Necking region exists only in ductile material • In mild steel, ABC are closer to each other, therefore it is known as Linear Elastic Metal, and Yield stress and elastic stress is taken as 250N/mm 2 • The Fracture or Failure in mild steel depends upon Percentage of carbon present in a steel The strain at yield stress is about 0.00125 or 0.125% • CD represents plastic Yielding i.e. it is the strain which occurs after ...

Structural Steel and Metal- Civil Engineering

Image
Structural Steel and Metals Civil Engineering Steel Steel is an alloy of iron and carbon, along with small amounts of other alloying elements or residual elements as well. The plain iron-carbon alloys (Steel) contain 0.002 - 2.1% by weight carbon. For most of the materials, it varies from 0.1-1.5%. There are 3 types of plain carbon steel: (i) Low-carbon steels: Carbon content in the range of < 0.3% (ii) Medium carbon steels: Carbon content in the range of 0.3 – 0.6%. (iii) High-carbon steels: Carbon content in the range of 0.6 – 1.4%. Properties Resistance to corrosion:  Is the ability of a material that resists against reaction with caustic elements that corrode or degrade the material. Ultimate Strength:  The maximum strength the material can withstand without breaking. Hardness It is defined as the resistance of a material to penetration or permanent deformation. It usually indicates resistance to abrasion, scratching, cutting or shaping. Ductility  It is the abilit...

The Great Wall of China: A Monumental Feat of Ancient Engineering

-
Here's another captivating fact about civil engineering: "The Great Wall of China: A Monumental Feat of Ancient Engineering" Stretching over 13,000 miles (21,000 kilometers) across rugged terrain, the Great Wall of China stands as one of the most impressive architectural achievements in human history. Built over centuries by successive dynasties, this colossal structure is a testament to the ingenuity, determination, and craftsmanship of ancient Chinese civil engineers. Constructed primarily as a defensive fortification to protect against invasions from nomadic tribes to the north, such as the Mongols and Xiongnu, the Great Wall comprises a series of walls, fortifications, and watchtowers, strategically positioned along China's northern border. The construction of the Great Wall began as early as the 7th century BCE, during the Warring States period, and continued for over two millennia, with various dynasties adding to and reinforcing its structure. The most famous s...
