determined by the initial conditionsof vibration. If T differs slightly from T, then, whatever be the initialform, the curve begins to change, and runs through all theforms shewn ; on loading the forks properly with small pelletsof wax the change takes place more slowly, until when Tbecomes equal… … Fig. 4. In a particular case, where l = \, the equation reduces to aparabola. 3. The figures in (c) and (d) shew the forms obtained whenT = i T, and 2 T = 3 T. There are many ways of drawing these curves geometrically ;and an excellent exercise for the student is to take a rectanglewhose sides…
