Graduate Apprentice Interview Questions and Answers for Freshers

Sensors are devices that detect and respond to input from the physical environment.

• Sensors can measure various parameters such as temperature, pressure, light, motion, proximity, etc.

• Examples of sensors include temperature sensors (thermocouples, thermistors), pressure sensors (piezoelectric sensors, strain gauges), light sensors (photodiodes, phototransistors), motion sensors (accelerometers, gyroscopes), proximity sensors (inductive, capacitive)

• Sensors can be categorized as...read more

Coolant is used to regulate the temperature of a machine or engine by absorbing heat and dissipating it elsewhere.

• Coolant prevents overheating of the machine or engine

• It absorbs heat generated by the machine or engine

• It dissipates the absorbed heat elsewhere

• Coolant also prevents corrosion and rusting of the machine or engine

• Examples of coolants include water, ethylene glycol, and propylene glycol

Time study is a method used to determine the time required to perform a specific task or activity.

• Time study involves observing and measuring the time taken to complete a task.

• It helps in setting standards for productivity and efficiency.

• Time study can be used to identify bottlenecks and improve processes.

• It is commonly used in industrial engineering and manufacturing.

• Example: Conducting a time study to determine the average time taken to assemble a product.

Data can be transferred through methods like wired connections, wireless connections, and cloud storage.

• Wired connections: using cables like Ethernet cables or USB cables to transfer data between devices.

• Wireless connections: using technologies like Wi-Fi, Bluetooth, or NFC to transfer data without cables.

• Cloud storage: uploading data to remote servers over the internet for access from anywhere.

• Data transfer protocols: using protocols like FTP, HTTP, or SMTP to transfer data ...read more

Viscosity is a measure of a fluid's resistance to flow.

• Viscosity is commonly referred to as thickness or resistance to flow.

• It is a property of fluids such as liquids and gases.

• High viscosity fluids flow slowly, while low viscosity fluids flow quickly.

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