3. A propeller pitch measuring device comprising a rectangular base plate, a circular protractor with a scale on its margin pivotally mounted on the face of said plate, an arm extending at right angles from the face of said plate and plane of rotation of said protractor, a hook adjacent ...
As will be explained, this mounting block 38 with its angle sensing unit 37 can also be used for determining steering axis inclination, direct reading of the positioning or angles of McPhearson struts and where there is no strut suspension can be used for determining the steering axis inclinati...
Experiment Description In a sheet, using a protractor, several marks are made to identify the angles to be detected. After that, the sensor is located at every drawn position to get a frame of data (1000 samples). This procedure is repeated 10 times. Then, for every angle, its batch of...
