Three metal rods are located relative to each other shown in figure - 6.101, where L_(1) + L_(2) = L_(3) Values of density and Young's modulus of the three materials are: (rho_(1)) = 2.7 xx 10^(3)kg//m^(3)y_(1) = 7 xx 10^(10)Pa, (rho_(1)) = 11.3 xx 10^(3)kg//m^(3)Y_(2) = 1.6 xx 10^(10) pa, (rho_(1)) = 8.8 xx 10^(3)kg//m^(3)Y_(3) = 11 xx 10^(10) pa If L_(3) = 1.5m What musht the ratio L_(1)//L_(_(2)) be if a sound wave is to travel the length of rods 1 and 2 in the same time as required to travel the length of rod 3 ? |
