10+ Manipal Technologies Interview Questions and Answers

The largest unit of density is g/cm^3. Water is not directly used in drilling due to its low density compared to drilling fluids.

• The largest unit of density is grams per cubic centimeter (g/cm^3)

• Water has a density of 1 g/cm^3, which is relatively low compared to drilling fluids

• Drilling fluids are used in drilling operations to provide lubrication, cooling, and pressure control

Vernier caliper is a precision measuring tool used to measure dimensions with high accuracy.

• Used to measure the internal and external dimensions of an object

• Consists of a main scale and a sliding vernier scale for more precise measurements

• Commonly used in engineering, machining, and manufacturing industries

• Example: Measuring the diameter of a shaft or the thickness of a sheet metal

Tolerance in CNC machining refers to the allowable deviation from a specified dimension or feature.

• Tolerance is the acceptable range of variation in a dimension or feature of a part.

• It ensures that parts fit together properly and function as intended.

• Tolerance is typically specified in units such as millimeters or inches.

• For example, a hole may have a tolerance of +/- 0.1mm, meaning it can be 0.1mm larger or smaller than the specified size.

• Tolerance can be affected by factors...read more

Newton's 1st law states that an object will remain at rest or in uniform motion unless acted upon by an external force. The 2nd law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• 1. Newton's 1st Law: An object will remain at rest or in uniform motion unless acted upon by an external force.

• 2. Newton's 2nd Law: The acceleration of an object is directly proportional to the net force acting o...read more

Four stroke engines have four stages (intake, compression, power, exhaust) per cycle, while two stroke engines have only two stages (compression, power).

• Four stroke engines have separate intake and exhaust strokes, while two stroke engines combine intake and exhaust in one stroke.

• Four stroke engines are more fuel efficient and produce less emissions compared to two stroke engines.

• Examples of four stroke engines include most car engines, while examples of two stroke engines in...read more

• Creating toolpaths for different machining operations

• Generating G-code for CNC machines

• Optimizing toolpaths for efficiency and accuracy

CNC stands for Computer Numerical Control. It is a technology used in manufacturing processes to control machine tools and equipment.

• CNC is a technology that uses computer software to control machine tools and equipment for manufacturing processes.

• CNC machines can perform tasks such as cutting, drilling, milling, and shaping materials with high precision and accuracy.

• CNC programming involves writing instructions for the machine to follow, specifying the movements and actions ...read more

Hydrostatic Head unit is a measure of water resistance in textiles. Formula: HH = height of water column in mm.

• Hydrostatic Head unit measures the pressure water exerts on a fabric.

• Formula: HH = height of water column in mm.

• Higher HH value indicates better water resistance.

• Example: Fabric with HH of 10,000mm can withstand a 10,000mm water column before leaking.

Packer is used for creating identical machine images for multiple platforms from a single source configuration.

• Packer helps in automating the process of creating machine images for different platforms like AWS, Azure, VMware, etc.

• It allows for consistent and repeatable builds, ensuring that the images are always up-to-date and secure.

• Packer can be integrated with configuration management tools like Ansible, Chef, or Puppet to further streamline the image creation process.

Bernoulli's principle states that as the speed of a fluid increases, its pressure decreases.

• The principle is based on the conservation of energy in a flowing fluid.

• It is commonly used in aviation to explain lift on an airplane's wings.

• Another example is the flow of water through a pipe where the pressure decreases as the velocity increases.

Iron carbon diagram shows the phases of iron and carbon at different temperatures.

• Iron carbon diagram is a graphical representation of the phases of iron and carbon at different temperatures.

• It shows the phases such as austenite, ferrite, cementite, and pearlite.

• The diagram helps in understanding the microstructure of steel and its properties.

• The diagram is used in heat treatment processes to control the properties of steel.

Hg is used in barometers due to its high density, low vapor pressure, and wide liquid range.

• Hg has a high density, allowing for accurate measurement of atmospheric pressure

• Hg has a low vapor pressure, ensuring that the liquid remains in the barometer tube

• Hg has a wide liquid range, making it suitable for measuring a wide range of pressures
