10+ Blue Yonder Interview Questions and Answers

Provisions checked for designing a beam/column according to IS Codes

• Cross-sectional dimensions

• Minimum reinforcement

• Maximum spacing of bars

• Clear cover to reinforcement

• Grade of concrete and steel

• Load-bearing capacity

• Bending moment and shear force

• Deflection limits

Permissible values for deflection in a structure according to IS provisions.

• The maximum permissible deflection for a structure is L/180 for live load and L/325 for total load.

• L is the span of the beam or slab in meters.

• The deflection limit is to ensure the safety and comfort of the occupants of the structure.

• The deflection limit varies for different types of structures and materials used.

• For example, the deflection limit for a reinforced concrete beam is different from that o...read more

To draw a Bending Moment diagram, one needs to determine the reactions, calculate the shear force and integrate it to get the bending moment.

• Determine the reactions at the supports

• Calculate the shear force at each section of the beam

• Integrate the shear force to get the bending moment

• Plot the bending moment diagram

Permissible stresses in concrete and steel as per IS codes.

• Permissible stress in concrete is 0.67 times the characteristic strength of concrete.

• Permissible stress in steel is 0.2 times the yield strength of steel.

• For example, if the characteristic strength of concrete is 30 N/mm², then the permissible stress in concrete would be 0.67 x 30 = 20 N/mm².

• Similarly, if the yield strength of steel is 415 N/mm², then the permissible stress in steel would be 0.2 x 415 = 83 N/mm².

Gutter is an example of open channel flow.

• Open channel flow is a flow of fluid in a channel with a free surface.

• Gutter is an open channel that carries rainwater from roofs to the ground.

• Closed pipe flow is a flow of fluid in a pipe with a closed surface.

• Examples of closed pipe flow include water supply pipes and sewage pipes.

IS 456 and IS 800 are codes and provisions related to concrete and steel design respectively.

• IS 456 provides guidelines for the design and construction of reinforced concrete structures.

• IS 800 provides guidelines for the design and construction of steel structures.

• IS 456 covers topics such as materials, loads, design of members, and detailing.

• IS 800 covers topics such as material properties, loads, design of members, and connections.

• Both codes are important for an Assistant E...read more

A distribution system in a town can be explained through a drawing.

• The distribution system starts at the water treatment plant

• Water is transported through pipes to storage tanks

• From storage tanks, water is distributed to homes and businesses

• The distribution system also includes valves, pumps, and meters

• The system may also include fire hydrants and water mains

• The drawing should show the flow of water and the location of key components

Channel flow is open flow with free surface while pipe flow is confined flow with closed surface.

• Channel flow occurs in open channels like rivers, canals, etc. while pipe flow occurs in closed conduits like pipes, tubes, etc.

• In channel flow, the fluid is exposed to the atmosphere and the surface is not fixed while in pipe flow, the fluid is confined and the surface is fixed.

• Channel flow is affected by gravity and surface tension while pipe flow is not affected by surface tens...read more

TCE stands for Trichloroethylene, a colorless liquid used as a solvent in various industries.

• TCE is commonly used in dry cleaning, metal degreasing, and as a refrigerant.

• It is a potent carcinogen and can cause serious health issues if not handled properly.

• TCE exposure can lead to liver and kidney damage, respiratory issues, and neurological problems.

• The EPA has set a maximum contaminant level of 5 parts per billion for TCE in drinking water.

• TCE has been linked to various envi...read more
