Homework Statement
Find equations of motion for mechanical system given by picture, where m = 1kg, k1 = 10, k2 = 25, b = 3 and natural lengths of springs are a1 = 1m, a2 = 2m. The whole system is in a gravitational field g = 9.81m/s^2
Homework Equations
The Attempt at a Solution
I came up with
[tex] m\ddot{y} = -k_2 y + k_1 (q-y) + mg \\
b\dot{q} = -k_1(q-y)
[/tex]
but whenever I try to model it in simulink it doesn't seem right.
