Hilti Intern Interview Questions and Answers

The load path of a power cylinder refers to the route through which the force is transmitted from the power source to the load being moved.

• The load path typically starts at the power source, such as a hydraulic pump or electric motor.

• The force is then transmitted through the power cylinder, which converts the fluid or electrical energy into mechanical force.

• Finally, the force is applied to the load being moved, such as...read more

A generator is a device that converts mechanical energy into electrical energy through electromagnetic induction.

• Generators work on the principle of electromagnetic induction.

• They consist of a coil of wire rotating in a magnetic field.

• The rotation of the coil induces a current in the wire, producing electricity.

• Generators are commonly used in power plants, wind turbines, and portable generators.

• Different types of gener

Components of a generator include engine, alternator, fuel system, voltage regulator, cooling and exhaust system, and control panel.

• Engine: provides power to the generator

• Alternator: converts mechanical energy into electrical energy

• Fuel system: supplies fuel to the engine

• Voltage regulator: maintains a constant voltage output

• Cooling and exhaust system: keeps the generator running at optimal temperature

• Control panel: all

The 2nd law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

• Entropy in a closed system tends to increase over time

• Heat will naturally flow from hot to cold objects

• Efficiency of energy conversion processes is limited by the 2nd law
