It was easy but tough

Q1. What is min coloumn width?
Ans. 
Min column width refers to the smallest width a column can be resized to in a table or spreadsheet.
• Min column width prevents columns from becoming too narrow to display content properly.

• It ensures readability and usability of the data in the table.

• For example, in Microsoft Excel, the default min column width is 8.43 units.

Q1. How to find yield strength of 8mm dia steel of 550 grade?
Ans. 
The yield strength of 8mm dia steel of 550 grade can be found using standard testing methods.
• Yield strength is the maximum stress a material can withstand without permanent deformation

• Standard testing methods like tensile testing can be used to determine the yield strength

• The 550 grade refers to the minimum yield strength of the steel

• Consulting the material's specification or conducting tests can provide the exact yiel

Q2. What is bleeding and segregation?
Ans. 
Bleeding and segregation are phenomena that occur in concrete during its placement and curing process.
• Bleeding is the process of water rising to the surface of freshly placed concrete due to the settlement of solid particles.

• Segregation refers to the separation of coarse aggregates from the rest of the concrete mix, resulting in an uneven distribution of materials.

• Bleeding can lead to a weakened surface layer and reduc...read more

Q3. Specify design mix ratios of various concrete mixes?
Ans. 
The design mix ratios of concrete mixes vary depending on the specific requirements and applications.
• Design mix ratios are determined based on factors such as strength, workability, durability, and environmental conditions.

• Common design mix ratios include 1:2:4 (cement:sand:aggregate) for general construction, 1:1.5:3 for reinforced concrete, and 1:0.5:1 for high-strength concrete.

• Different types of concrete mixes, suc...read more

Q4. Draw shear force and bending moment diagrams
Ans. 
Shear force and bending moment diagrams are graphical representations of the internal forces and moments in a structural element.
• Shear force diagram shows the variation of shear force along the length of the element.

• Bending moment diagram shows the variation of bending moment along the length of the element.

• Shear force and bending moment diagrams are commonly used in structural analysis and design.

• These diagrams help e...read more

Q1. How many brickes need in 1m3
Ans. 
The number of bricks needed in 1m3 depends on the size of the bricks being used.
• The number of bricks in 1m3 will vary based on the size of the bricks. Standard brick size is 190mm x 90mm x 90mm.

• For standard size bricks, approximately 500 bricks are needed in 1m3.

• To calculate the number of bricks needed, divide the volume of 1m3 by the volume of one brick.

Q2. Fos for concrete
Ans. 
Fos is a type of admixture used in concrete to improve its workability and durability.
• Fos is a water-reducing admixture that helps in reducing the water content in concrete mixtures.

• It improves the workability of concrete, making it easier to place and finish.

• Fos also enhances the durability of concrete by reducing permeability and increasing strength.

• Examples of Fos for concrete include polycarboxylate-based admixture

Q2. What are the values of Compressive & Tensile Shear Stress on a Singly Reinforced Beam in LSM method?
Ans. 
Compressive shear stress is zero while tensile shear stress is equal to the shear force divided by the cross-sectional area of the beam.
• Compressive shear stress is zero in a singly reinforced beam according to the Limit State Method (LSM).

• Tensile shear stress is calculated by dividing the shear force by the cross-sectional area of the beam.

• For example, if the shear force acting on the beam is 10 kN and the cross-sectio...read more
