LM Wind Power Interview Questions and Answers

The value of 1/infinity is 0.

• The value of 1/infinity is considered to be zero.

• In mathematics, infinity is not a number but a concept representing an unbounded quantity.

• When we divide any finite number by infinity, the result tends to zero.

• For example, 1/∞ = 0, 10/∞ = 0, -5/∞ = 0.

Glass is a solid material that is transparent, brittle, and has no definite shape or volume.

• Glass is made by melting silica, soda ash, and lime together at high temperatures.

• It is a good insulator and can be used for windows, lenses, and mirrors.

• Glass can be colored or clear, and can be shaped into various forms.

• It is fragile and can break easily, but can also be tempered to increase its strength.

• Glass is non-porous and does not absorb liquids or gases.

• It is also resistant to...read more

The engineer started with education and training in engineering principles and practices. Turbines and propellers work by converting fluid or air pressure into rotational motion.

• Engineers typically start with a degree in engineering or a related field, followed by on-the-job training and experience.

• Turbines work by using the pressure of a fluid, such as steam or water, to turn a rotor and generate electricity. The rotor is connected to a shaft that drives a generator.

• Propelle...read more

Problem solving techniques are methods used to identify, analyze and solve problems.

• Root cause analysis

• Brainstorming

• Fishbone diagram

• Pareto chart

• 5 Whys

• DMAIC

• PDCA

• Kaizen

• TRIZ

A linked list in Java is a data structure that consists of a sequence of elements where each element points to the next element in the sequence.

• Each element in a linked list is called a node.

• Nodes in a linked list are connected through pointers or references.

• Linked lists can be singly linked (each node points to the next node) or doubly linked (each node points to both the next and previous nodes).

• Example: LinkedList list = new LinkedList();

Materials can be qualified based on their physical, mechanical, chemical, and thermal properties.

• Qualify materials based on physical properties such as density, hardness, and color.

• Consider mechanical properties like strength, elasticity, and toughness.

• Examine chemical properties such as reactivity, corrosion resistance, and stability.

• Evaluate thermal properties including conductivity, expansion coefficient, and melting point.

Darcy's law is a formula used to describe the flow of fluids through porous media.

• Darcy's law states that the flow rate of a fluid through a porous medium is directly proportional to the pressure drop and the permeability of the medium, and inversely proportional to the viscosity of the fluid.

• It is commonly used in hydrogeology to calculate groundwater flow.

• The formula is Q = -KA(dP/dL), where Q is the flow rate, K is the permeability, A is the cross-sectional area, dP/dL is ...read more

The plane's capacity is determined by its size, weight, and design.

• The size of the plane determines how many passengers and cargo it can carry.

• The weight of the plane affects its fuel efficiency and range.

• The design of the plane can also impact its capacity, such as the number of seats or cargo hold space.

• For example, a Boeing 747 has a capacity of around 660 passengers, while a smaller regional jet may only hold around 50 passengers.
