Madhukamal Construction Interview Questions and Answers

A motor is a device that converts electrical energy into mechanical energy through electromagnetic principles.

• Motors are used in various applications such as electric vehicles, industrial machinery, and household appliances.

• The working principle of a motor involves the interaction between magnetic fields and electric currents.

• Electric current flowing through a coil in the motor creates a magnetic field, which interacts with the magnetic field of a permanent magnet or electrom...read more

The percentage of carbon in cast iron varies from 2.1% to 4.0%.

• Cast iron is a strong and brittle material used in construction and manufacturing.

• The carbon content in cast iron gives it its unique properties.

• Higher carbon content makes cast iron more brittle and less ductile.

• Gray cast iron typically contains 2.1% to 4.0% carbon.

• White cast iron has a higher carbon content, usually above 4.0%.

The control panel for a HMC machine is a user interface that allows operators to input commands and control the machine's operations.
