*Sign up*Problem 11.1
Consider the undamped single-DOF system shown below, where
m
=
2
kg
and
k
1
=
1600
N
/
m
. The applied force, f(t), has an impulse of
I
=
5
N
⋅
sec
.
a)
Derive the EOM for the system in terms of the generalized coordinate x.
The springs are unstretched when x = 0.
b)
If
f
(
t
)
=
I
δ
(
t
)
(where
(
t
)
is the Dirac delta function) and
k
2
=
k
1
,
determine the maximum response
x
max
.
c)
If
f
(
t
)
is the pulse function shown below and
k
2
=
k
1
, determine the
maximum response
x
max
