Kreate Energy RPA Developer Interview Questions and Answers

SFD and BMD illustrate internal forces and moments in a cantilever beam under loads.

• Shear Force Diagram (SFD) shows how shear force varies along the length of the beam.

• Bending Moment Diagram (BMD) illustrates how bending moments change along the beam.

• For a cantilever beam with a point load at the free end, SFD is constant and negative, while BMD is a linear function.

• If a distributed load is applied, SFD will have a tri...read more

Tolerance refers to the permissible limit of variation in a physical dimension or property of a material or component.

• Tolerance is crucial in engineering to ensure parts fit together correctly.

• It defines the acceptable range of variation in dimensions, such as +/- 0.01 mm.

• For example, in machining, a tolerance of 0.1 mm might be acceptable for a non-critical part.

• In electronics, tolerance can refer to the allowable var...read more

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 ...read more

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 meltin...read more
