The end E of the arm A is attached to the draw-bar pullrecorder, and moves in the direction indicated, proportionately tothe draw-har pull. The wheel is set so that for zero draw-har pul3it is at right angles with the… … i -23- shows the relation, expressed by the equationA R L where A = Area under draw-lDar pull curre. R = Circumference of wheel. L = Length of arm A.Hence, the angular travel of the wheel is directly proportionalto the area under the pull curve. With the proportions given thewheel and arm, one…
