The speed of sound in air is approximately 340 m/s. The speed of sound in steel is approximately 5900 m/s. If your friend strikes one end of a steel pipe with a hammer while you listen at the other end, you will hear two distinct sounds: one traveling through the air and the other traveling through the steel pipe. If the pipe is 700 meters long, how much time elapses between the two sounds?

Strain Gauges

All the components used in civil engineering and mechanical engineering applications undergo deformations due to induced internal stresses under the application of external loads. Under repeated application of loads, there is a high possibility of failure of the components. Hence, periodic monitoring of the components and determination of stresses are very important.

mass of 1 kg is pushed by a force of 2 N and reaches a terminal velocity of 1 m/s on an oil slick horizontal floor. Determine the time constant of the system. Once this is known, how long will it take to reach 95% of its final speed if it starts from rest? Sketch a plot of the speed response of the mass. Indicate on the plot the final value and how the time constant and initial slope of the response are related.
