Driven oscillations in a multiple spring-mass system.
3A60.24 • B+20+35
Driven oscillations in a multiple spring-mass system. Four ballistic carts are linked with identical springs and driven by a variable speed motor. The system exhibits four normal modes. With k=m=1, the modes and frequencies are approximately: 1) f=0.62 (symmetric mode) 2) f=1.18 3) f=1.62 4) f=1.90 (anti-symmetric mode) Note: k = spring constant, m = mass, f = frequency
