Compression members are structural elements subjected to axial compressive forces.
Compression members are used in buildings, bridges, and other structures to support loads in compression.
Common examples include columns, struts, and trusses.
The design of compression members involves considerations such as buckling, stability, and material strength.
Slenderness ratio is a measure of a structural element's stability under compression, and codes such as ACI, AISC, and Eurocode are commonly used in design.
Slenderness ratio is the ratio of the effective length of a column to its radius of gyration.
Different codes have different criteria for slenderness ratio limits to ensure structural stability.
Examples of codes used for slenderness ratio calculations include ACI (Am...

I applied via Recruitment Consulltant and was interviewed in Apr 2023. There were 3 interview rounds.
Molding is a manufacturing process where a liquid or pliable material is poured into a mold to create a specific shape.
Molding involves heating a material until it becomes pliable, then shaping it using a mold.
Common types of molding include injection molding, blow molding, and compression molding.
Examples of molded products include plastic bottles, car parts, and toys.
Plastic parts are developed using methods like injection molding, blow molding, and thermoforming.
Injection molding is a common method where molten plastic is injected into a mold.
Blow molding is used for hollow parts like bottles, where plastic is blown into a mold.
Thermoforming involves heating a plastic sheet and shaping it over a mold.
Other methods include rotational molding, extrusion, and compression molding.
Shrinkage in plastic refers to the reduction in size of a plastic part after it has been molded.
Shrinkage occurs as the plastic cools and solidifies after being injected into a mold.
It is important to account for shrinkage when designing molds and parts to ensure proper dimensions.
Factors affecting shrinkage include material type, mold temperature, cooling rate, and part geometry.
Common methods to compensate for shrink...
NPD in industry refers to New Product Development, which involves the process of designing, creating, and bringing new products to market.
NPD involves identifying market opportunities and customer needs
It includes concept development, design, prototyping, testing, and commercialization
NPD teams often collaborate with various departments such as marketing, engineering, and manufacturing
Successful NPD can lead to increas...
Costing of complete products can be calculated by considering materials, labor, overhead, and profit margin.
Calculate the cost of materials required for the product
Estimate the labor costs involved in manufacturing the product
Factor in overhead costs such as utilities, rent, and equipment depreciation
Add a profit margin to cover additional expenses and generate profit
Consider any additional costs such as shipping, pack...
Gate & runner in molding are channels through which molten material is injected into the mold cavity.
Gate is the opening through which molten material enters the mold cavity
Runner is the channel that connects the gate to the sprue or main injection point
Proper design of gates and runners is crucial for ensuring even distribution of material and preventing defects
Examples: Submarine gate, edge gate, hot runner system
The purpose of gate & runner in molding is to control the flow of molten material into the mold cavity.
Gate controls the flow of molten material into the mold cavity
Runner distributes the molten material throughout the mold
They help in achieving proper filling of the mold and reducing defects like air pockets or incomplete filling
Different types of gates and runners are used based on the molding process and material be
Moment and shear force diagrams are graphical representations of the internal forces acting on a structural element.
Moment diagram shows the variation of bending moment along the length of the beam.
Shear force diagram shows the variation of shear force along the length of the beam.
Both diagrams are essential for designing and analyzing structures.
They help in determining the maximum bending moment and shear force that ...
The difference between == and === is that == compares the values of two variables, while === compares both the values and the data types.
The == operator performs type coercion, meaning it converts the operands to a common type before comparison.
The === operator does not perform type coercion and requires both the values and the data types to be the same for a true comparison.
For example, 1 == '1' returns true because t...
MCB is a miniature circuit breaker used for low currents, while MCCB is a molded case circuit breaker used for higher currents.
MCB is designed for low currents, typically up to 100A, while MCCB is designed for higher currents, typically up to 2500A.
MCB is a compact device with fixed trip settings, while MCCB is larger and has adjustable trip settings.
MCB is commonly used in residential and commercial applications, whil...
A relay is an electrically operated switch that uses an electromagnet to mechanically operate the switch contacts.
Relays are used to control high power circuits with a low power signal.
When the coil of the relay is energized, it creates a magnetic field that causes the switch contacts to close or open.
Relays are commonly used in automotive applications, industrial controls, and home appliances.
There are different types...
