// SAMPLE PROBLEM 6/12

// Given data
m_A=3;// kg
m=2;// kg
k=0.060;// The radius of gyration in m
k=1.2;// The spring stiffness in kN/m
F=80;// N
g=9.81;// The acceleration due to gravity in m/s^2
// Calculation
// dT_rack=3a dx
// dT_gear=0.781a dx
// dV_rack=29.4 dx
// dV_gear=9.81 dx
// dV_spring=24 dx
// Canceling dx and solving for a give
