I applied via Referral and was interviewed before Sep 2022. There were 5 interview rounds.
It was online. It contains I think 50 question and I got enough time to solve them, may be 1hour I think. Question was normal, not that much difficult, like SSC CGL. There was one another test followed by aptitude test i.e personality test. Also online, that contains situation based questions, designed to know your approach to deal with the problem. Sometimes either we try to solve the problem or sometime we try to avoid the problem.
Various materials such as metals, plastics, ceramics, and composites can be used to design a SPM.
Metals like steel and aluminum are commonly used for strength and durability
Plastics like ABS and PVC are used for their lightweight and corrosion resistance
Ceramics like alumina and zirconia are used for their high temperature resistance
Composites like carbon fiber and fiberglass offer a combination of strength and light w
Bearings are components that allow for smooth rotation or movement between two parts.
Types of bearings include ball bearings, roller bearings, plain bearings, and fluid bearings.
Ball bearings use balls to reduce friction between two surfaces.
Roller bearings use cylindrical rollers to support radial and axial loads.
Plain bearings have a sliding surface instead of balls or rollers.
Fluid bearings use a thin layer of liqui
Types of motors include DC motors, AC motors, stepper motors, and servo motors.
DC motors: Direct current motors that convert electrical energy into mechanical energy.
AC motors: Alternating current motors that use alternating current to produce rotational motion.
Stepper motors: Motors that move in precise increments or steps.
Servo motors: Motors that use feedback to control the position and speed of the motor.
Motors selection criteria involve factors like power requirements, speed, torque, size, efficiency, and cost.
Consider power requirements for the specific application
Determine the required speed and torque for the motor
Take into account the size constraints of the motor
Evaluate the efficiency of the motor to minimize energy loss
Compare costs of different motor options
