Mechatronics Practice Test 2

1. The Samuel motion sensor works on which principle?

2. What is the mean value of a distance observation set taken by a distance measurement sensor?
Observations={3,3.213,3.11,2.97}

3. What is the frequency range of the ultrasonic sound waves used by the ultrasonic sensors?

4. What is the relative error of an observation taken by an ultrasonic sensor which predicts the distance of an object to be 2.3 cm but the actual value is 2.1cm?

5. Which among the following is a correct statement regarding “Mechatronic system”?

6. A car moves with a speed of 30 km/hr. What will be the speed of the same car measured by a speed sensor which is placed in a truck which is moving with a speed of 20 km/hr in the same direction?

7. A car moves with a speed of 60 km/hr. What will be the speed of the same car measured by a speed sensor which is placed in a bicycle which is moving with a speed of 12 km/hr in the opposite direction?

8. What is the relative accuracy ratio of an observation taken by a IR(Infrared) sensor which predicts the distance of an object to be 4.16cm but the actual distance is 4.09cm?

9. Primitive methods should be preferred over mechatronic systems for short term manufacturing.

10. What is the standard capacity of tension load cells to measure load?
