Clinometer

This is a simple clinometer designed in SW2003 for a 9th grade math project focused on trigonometric functions in right triangles. Also known as an inclinometer, this instrument measures elevation or height of objects. As part of our project, we used formulas learned with the clinometer to determine the height of unknown objects. When printing, scale up 17x. A forester uses a clinometer by measuring straight-line distance D from observation point O to object and then using the instrument to measure angle a between O and object's top. Similarly, they measure angle b between O and object's bottom. Multiplying D by tangent of a gives the height above O, and multiplying D by tangent of b provides depth below O. Adding both heights yields total height (H) of the object.
