Q1: Which of the following transducers is most commonly used for the measurement of shock and vibration ?

ANS:C - Accelerometer

The correct answer is "Accelerometer." Accelerometers are specifically designed to measure acceleration, which includes shock and vibration. They are widely used in various industries and applications to monitor and measure the dynamic forces experienced by objects due to motion, impact, or vibration. Accelerometers can detect changes in acceleration along one or more axes and convert these changes into electrical signals that can be recorded and analyzed. Linear variable differential transducers (LVDTs) are displacement sensors and are not specifically designed to measure shock and vibration. Dial gauges are mechanical devices used to measure linear displacement and are not suitable for measuring dynamic forces like shock and vibration. Therefore, the most appropriate choice for measuring shock and vibration among the options provided is the accelerometer.
