4. A simple accelerometer can be made froma U-tube containing water as in
200mm
Figure. 1) When the acceleration of a car with the U-tube is a [m/s?] in
the horizontal direction (x-direction), find the relation between a and the
level difference h [m]. 2) When H
vertical tubes at a = 0 is 250 mm, find the maximum accelaration which
h
= 400 mm and the water level ho for both
H
h。
can be measured by this accelarometer. Use g = 9.8 m/s? and pwater =
1000 kg/m?.
