INNOVATIVE WORK

CLINOMETER



  



'My innovative work is clinometer' I made clinometer based on chapter 'Trigonometry' in tenth std. Clinometer help to find the angle of elevation and using it  the height of the buildings,tree or tower can be measured, without actually measuring it.

CLINOMETER

Clinometer is an instrument that measures vertical slopes , usually the angle between ground or the observer and a tall object.


CONSTRUCTION OF CLINOMETER

STEP 1 : Get a protractor with one straight edge.
STEP 2 : Tape a straw along the straight edge of protractor.
STEP 3 : Tie a string through the small hole on the straight that in directly across from the 0                                 degree mark on the protractor.This may also be labelled as 90 degree.
STEP 4 : Attach a bead or small stone at the end of the string.


My aim is to find the height
of the building in the model. Angle of elevation is found using clinometer and it is 47 degree.Using the trigonometric ratio tan , the height of the building is got as 30 cm.
