A transverse sinusoidal wave is generated at one end of a long,horizontal string by a bar that moves up and down through adistance of 1.7 cm. The motion is continuous and is repeatedregularly 160 times per second. The string has linear density 460g/m and is kept under a tension of 140 N. Find the maximum value of(a) the transverse speed u and(b) the transverse component of the tensionT. (c)Show that the two maximum valuescalculated above occur at the same phase values for the wave. Whatis the transverse displacement y of the string at thesephases? (d) What is the maximum rate of energytransfer along the string? (e) What is thetransverse displacement y when this maximum transferoccurs? (f ) What is the minimum rate of energytransfer along the string? (g) What is thetransverse displacement y when this minimum transferoccurs?
