Ramky Group Senior Engineer Interview Questions and Answers

BMD for sway frame is a diagram showing the variation of bending moment along the length of the frame.

• BMD for sway frame will have a shape similar to a zigzag pattern due to the presence of sway in the frame.

• The bending moment will be maximum at the points where the frame experiences maximum sway.

• The BMD can be drawn by analyzing the internal forces and moments acting on the frame.

Drawing piperack elevations involves creating detailed drawings of the structure from different viewpoints.

• Start by determining the dimensions and layout of the piperack

• Use software like AutoCAD to create accurate and detailed drawings

• Include all necessary details such as pipe sizes, supports, and connections

• Label all components clearly for easy understanding

• Review and revise the drawings as needed for accuracy

The manufacturing of cement involves chemical reactions with water, resulting in the durability of concrete.

• Cement is made by heating limestone, clay, and other materials in a kiln

• The chemical reaction between cement and water, known as hydration, results in the hardening of concrete

• The durability of concrete depends on factors such as the water-cement ratio, curing time, and quality of materials used

Calculate deflection at free end of cantilever beam with point load at end

• Use the formula: δ = (PL³)/(3EI)

• P is the point load at the end

• L is the length of the cantilever beam

• E is the modulus of elasticity of the beam material

• I is the moment of inertia of the beam's cross-sectional area

• Example: A steel cantilever beam with a length of 2 meters and a point load of 500 N at the end has a deflection of 0.104 mm

Camber is the slope provided to the road surface to drain off rainwater. It is achieved by raising the center of the road surface.

• Camber is the curvature provided to the road surface to ensure proper drainage of rainwater.

• It is achieved by raising the center of the road surface.

• The amount of camber depends on the width of the road and the expected rainfall.

• The steps for the construction of a road include surveying, cle...read more

Admixtures are chemicals added to concrete to enhance its properties. They affect the workability, strength, and durability of concrete.

• Admixtures are added to concrete to improve its quality and performance.

• They can affect the setting time, workability, strength, and durability of concrete.

• Examples of admixtures include water reducers, accelerators, retarders, air-entraining agents, and superplasticizers.

Hoop stress is the stress exerted circumferentially in a cylindrical or spherical object. Reinforcement in a dome can be provided by using steel bars or mesh.

• Hoop stress is caused by the pressure inside the object and is calculated using the formula P*r/t, where P is the pressure, r is the radius, and t is the thickness of the object.

• In a dome, reinforcement can be provided by using steel bars or mesh that are placed i...read more

Estimation and costing involves calculating the expenses of a project. No. of bricks required in 1 m3 of brickwork depends on the size of the bricks. There are various types of contracts in construction.

• Estimation and costing involves calculating the expenses of a project, including materials, labor, and other costs.

• No. of bricks required in 1 m3 of brickwork depends on the size of the bricks used. For example, if stan...read more
