R&D Executive Interview Questions and Answers

Surface active agents, or surfactants, work by reducing the surface tension between two substances. There are four main types of surfactants.

• Surfactants reduce surface tension between two substances

• Types of surfactants include anionic, cationic, nonionic, and amphoteric

• Anionic surfactants are commonly used in cleaning products

• Cationic surfactants are often used in fabric softeners

• Nonionic surfactants are used in laundry detergents and shampoos

• Amphoteric surfactants are used i...read more

Methods for sheet forming process include bending, deep drawing, and roll forming.

• Bending: involves bending the sheet along a straight axis to create a desired shape

• Deep drawing: involves stretching a sheet over a die to form a complex shape

• Roll forming: involves passing a sheet through a series of rollers to gradually shape it

A MOSFET is a type of transistor used in electronic devices to control the flow of electrical current. A battery works by converting chemical energy into electrical energy.

• MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

• It is commonly used in amplifiers, switches, and digital circuits.

• A battery works by converting chemical energy stored in its electrodes into electrical energy through a chemical reaction.

• The flow of electrons from the battery creates an el...read more

Types of manufacturing processes include casting, machining, forming, joining, and additive manufacturing.

• Casting: involves pouring molten material into a mold to create a desired shape (e.g. metal casting)

• Machining: involves removing material from a workpiece using cutting tools (e.g. milling, turning)

• Forming: involves shaping a material without removing any material (e.g. bending, stamping)

• Joining: involves combining multiple pieces to create a single product (e.g. welding,...read more
