Question

A mass weighing 96 lb is attached to a spring hanging from the
ceiling and comes to rest at its equilibrium position. At time
t=0, an external force of F(t) = 3**cos(**4t) lb is
applied to the system. If the spring constant is 10 lb/ft and the
damping constant is 3 lb-sec/ft, find the steady-state solution
for the system.

Use g=32 ft/sec^2

Answer #1

A mass weighing 32 lb is attached to a spring hanging from the
ceiling and comes to rest at its equilibrium position. At time t=0,
an external force of F(t) = 3cos(2t) lb is applied to the system.
If the spring constant is 10lb/ft and the damping constant is 4
lb-sec/ft, find the steady state solution for the system. Use g =
32 ft / sec^2

A spring is stretched by 9 in by a mass weighing 18 lb. The mass
is attached to a dashpot mechanism that has a damping constant of
0.15 lb⋅s/ft and is acted on by an external force of 6cos(8t)
lb.Determine the steady state response of this system. Use 32
ft/s^2 as the acceleration due to gravity. Pay close attention to
the units. Leave answer in terms of exact numbers(no decimals).

when a mass of 2 kg is attached to a spring whose constant is 32
N/m, it come to rest in the equilibrium position. at a starting
time t=0, an external force of y=80e^(-4t)*cos(4t) is applied to
the system. find the motion equation in the absence of damping.

A mass of 1 slug, when attached to a spring, stretches it 2 feet
and then comes to rest in the equilibrium position. Starting at t =
0, an external force equal to f(t) = 4 sin(4t) is applied to the
system. Find the equation of motion if the surrounding medium
offers a damping force that is numerically equal to 8 times the
instantaneous velocity. (Use g = 32 ft/s2 for the
acceleration due to gravity.)

A body weighing 1 [kg] is attached to a spring hanging from the
ceiling. The spring stiffness constant is k = 6k = 6 [N / m]. The
medium surrounding the system offers resistance proportional to
body speed with a damping constant: µ = 5μ = 5 [N.s / m]. The
body's center of mass is initially at a distance of 1 [m] below the
equilibrium point, then the body is released by printing an upward
velocity of 44 [m...
