Design Trainee Interview Questions and Answers

Histrasis is the property of a material to resist change in shape or size under stress. Viscosity is the measure of a fluid's resistance to flow.

• Histrasis is important in materials science and engineering as it determines the strength and durability of materials.

• Viscosity is important in fluid mechanics and is measured in units such as poise or centipoise.

• Examples of high viscosity fluids include honey and molasses, while low viscosity fluids include water and gasoline.

• Viscos...read more

Thermodynamics process involves the study of energy transfer and conversion in physical systems.

• It deals with heat, work, and energy interactions in systems.

• Examples include heat engines, refrigerators, and air conditioners.

• First law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.

• Second law of thermodynamics states that entropy in a closed system will always increase over time.

Design parameter of a tool refers to the specific characteristics or features that determine its functionality and performance.

• Design parameters include dimensions, materials, weight, and ergonomics.

• For example, in the design of a hammer, the length and weight of the handle, the shape and hardness of the head, and the grip design are all important parameters.

• Other parameters may include durability, ease of use, safety features, and cost-effectiveness.

• Design parameters are cru...read more

The third angle is the angle that completes a triangle when the measures of the other two angles are known.

• The sum of the three angles in a triangle is always 180 degrees.

• To find the third angle, subtract the measures of the other two angles from 180 degrees.

• For example, if one angle is 60 degrees and another angle is 40 degrees, the third angle would be 180 - 60 - 40 = 80 degrees.

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is measured in force per unit area (e.g. N/m^2 or Pascals)

• Strain is a dimensionless quantity representing the amount of deformation

• Stress and strain are related by the material's elastic modulus, which describes how much a material will deform under a given amount of stress

• Example: Stretching a rubber band causes stress on the material, resulting in strain as the ban...read more
