FREE ASQ Certified Quality Inspector & Reliability Engineer Questions and Answers
Which of the following factors should a reliability engineer take into account first when evaluating failures during a reliability test program?
When assessing failures during a reliability test program and observing a constant hazard rate.
Which of the following hardness tests is most appropriate for use with rubber and plastic?
Durometer hardness testing is best suited for measuring the hardness of materials such as plastic and rubber. Durometer hardness tests are widely used in the plastics and rubber industries to assess the hardness and stiffness of these materials.
What is the MOST accurate way to check that a design satisfies the maintainability requirement?
By demonstrating at the customer's facility is the most accurate method to verify that the maintainability requirement of a design is being met. Demonstrating the maintainability of a design at the customer's facility allows the design team to assess the real-world maintainability performance in the actual operational environment.
Which of the subsequent transfer type measuring instruments doesn't normally have a measuring scale?
Spring calipers, telescoping gauges, and joint caliper transfer type measuring devices typically do not have a measuring scale integrated into the tool itself. Instead, they rely on a separate measuring instrument, such as a ruler, micrometer, or vernier caliper, to read and record the measured values.
Which of the following is the primary justification for the adoption of Quality Function Deployment (QFD)?
The main reason for the use of Quality Function Deployment (QFD) is to implement the Voice of the Customer (VOC). QFD is a systematic and customer-focused approach used in product and service development to ensure that customer needs, requirements, and expectations are translated into specific design and engineering characteristics.
Which of the following quantitative techniques DOESN'T applicable to evaluating the reliability of actual systems or components?
Statistical allocation of reliability goals using quantitative methods is primarily used during the design and development phase of a system or component. It helps in setting reliability targets or goals for individual components, subsystems, or the entire system to ensure that the overall system meets its reliability requirements.
Which of the following can concurrently measure size and location?
Coordinate Measuring Machines (CMMs) are capable of measuring both size and location simultaneously. CMMs are sophisticated metrology tools used to accurately measure the dimensional characteristics of objects or components.
Which of the following needs to be true for a process to be in a statistically controlled state?
To consider a process to be in a state of statistical control, all subgroup averages and ranges (or other appropriate statistics) must be within control limits, and certain conditions must be met. These conditions are typically assessed using control charts, which are powerful tools used in statistical process control (SPC) to monitor and evaluate process stability.
You are looking at a gage block set's calibration history. They have been calibrated every six months for the past few years without any errors. They are also only utilized for non-critical measures and no more than once every week.
What should be done in this situation?
It's essential to maintain proper records of calibration results and establish a well-documented calibration process to ensure that the gage blocks are traceable and consistently meet the required accuracy standards. Additionally, the calibration interval should always be subject to review and adjustment based on changes in usage patterns, environmental conditions, or other factors that may impact the gage block's performance over time.
A system for reporting failures and taking corrective action should make sure that all necessary actions are performed to:
A Failure Reporting and Corrective Action System (FRACAS) is a structured approach used by organizations to identify, investigate, analyze, and address failures or issues that occur with their products, processes, or systems. The primary goal of FRACAS is to collect information about failures, analyze the root causes, and implement appropriate corrective actions to prevent future occurrences.
What is involved in failure modes and effects analysis?
Failure Modes and Effects Analysis (FMEA) is a systematic and proactive approach used to identify and analyze potential failure modes in a product, process, or system, and their potential effects on performance, safety, or reliability. While FMEA involves identifying failure modes and their causes, it is not specifically focused on the study of the physics of failure to determine exactly how a product fails.
What is 68 degrees Fahrenheit in centigrade?
To convert 68 degrees Fahrenheit to Celsius (Centigrade), you can use the following formula:
°C = (°F - 32) × 5/9
Let's apply the formula:
°C = (68 - 32) × 5/9
°C = 36 × 5/9
°C = 180/9
°C = 20
So, 68 degrees Fahrenheit is approximately equal to 20 degrees Celsius.
Which type of failure is typically minimized by routine component overhaul and replacement?
"Wear out" refers to the gradual deterioration and degradation of a component or system over time due to repeated use, stress, or fatigue. It is a common form of failure that occurs in mechanical systems, machines, and equipment.
Which of the many terms in the binomial expansion can be easily determined using Pascal's triangle?
Pascal's triangle provides a simple and efficient method for determining the coefficients of the various terms in the binomial expansion of a binomial expression. The coefficients in the binomial expansion are also known as binomial coefficients or combination numbers.
Which of the following situations allows for capability evaluation when a control chart is employed on a new process?
When a control chart is used on a new process, capability can be assessed after the process is shown to be in control. Control charts are initially used to monitor the process and determine its stability and consistency. Once the process is demonstrated to be in a state of statistical control, meaning that it is stable and predictable with only common causes of variation present, the next step is to assess its capability.
Which of the following DOES NOT contribute to effective teamwork?
Company management's direct participation as a team member is not a necessary condition for team effectiveness. While having management involvement in teams can be beneficial in some situations, effective teams can exist and perform well without direct participation from company management.
