Knorr-Bremse Interview Questions and Answers

Fatigue analysis of weld is performed by applying cyclic loading to the weld and analyzing stress concentrations.

• Apply cyclic loading to the weld to simulate real-world conditions

• Analyze stress concentrations at critical points using finite element analysis

• Calculate fatigue life based on stress levels and material properties

• Consider factors such as weld geometry, residual stresses, and material defects

• Use standard...read more

Yes, it is possible to call an ISR from another ISR.

• Calling an ISR from another ISR is known as nesting ISRs.

• It is important to carefully manage the nesting depth to avoid stack overflow.

• Nested ISRs can introduce complexity and potential issues, so it should be used judiciously.

The unit of hydraulic pressure is Pascal (Pa).

• The unit of hydraulic pressure is commonly expressed in Pascal (Pa).

• Other units used for hydraulic pressure include pounds per square inch (psi) and bar.

• 1 Pascal is equal to 1 Newton per square meter.

• Hydraulic systems typically operate at pressures ranging from a few hundred to several thousand psi.

8 bit microprocessor is called so because it processes data in 8 bit chunks.

• 8 bit microprocessor processes data in 8 bit chunks at a time

• It can handle data in 8 bit binary format

• Examples include Intel 8080, Zilog Z80, and MOS Technology 6502

Storage classes in C define the scope and lifetime of variables.

• Auto: Default storage class for local variables

• Register: Requests a variable to be stored in a register for faster access

• Static: Preserves the value of a variable between function calls

• Extern: Allows access to a variable declared in another file

• Thread Local Storage (TLS): Provides each thread with its own copy of a variable

UDS stands for Unified Diagnostic Services, a protocol used in automotive industry for communication between ECUs.

• UDS is used for diagnostic communication between ECUs in vehicles.

• It is based on the ISO 14229 standard.

• UDS allows for diagnostic services such as reading and clearing fault codes, and accessing ECU data.

• It uses a request-response mechanism, where the diagnostic tool sends a request and the ECU respond...read more
