Knorr-Bremse Interview Questions and Answers
23 Interview questions
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...
The number of modes to extract in modal analysis is typically determined based on the desired accuracy of the analysis and the computational resources available.
Consider the complexity of the structure being analyzed - more complex structures may require more modes to be extracted
Take into account the desired accuracy of the analysis - higher accuracy may require more modes to be extracted
Evaluate the computationa...
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
Macro code to set a bit in embedded software
Define a macro using bitwise OR operator to set a specific bit in a register
Example: #define SET_BIT(reg, bit) ((reg) |= (1 << (bit)))
Call the macro with the register and bit number as arguments
Preprocessor directives are commands used by the preprocessor to perform tasks before the actual compilation process begins.
Preprocessor directives start with a # symbol.
They are used to include header files, define constants, and perform conditional compilation.
Examples include #include, #define, #ifdef, #ifndef, #endif, #pragma, etc.
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
Positioning tolerance refers to the allowable deviation from the desired position of an object or component.
Positioning tolerance is a measure of how much an object or component can deviate from its intended position without affecting its functionality.
It is typically specified in terms of a maximum allowable distance or angle.
For example, in manufacturing, positioning tolerance is used to ensure that parts fit to...
Kaizen is a Japanese business philosophy of continuous improvement involving all employees.
Kaizen focuses on making small, incremental changes to processes to improve efficiency and quality.
It involves employees at all levels of the organization in identifying and implementing improvements.
Kaizen promotes a culture of continuous learning and innovation.
Examples of kaizen include implementing a new workflow to redu...
