There is no extra information. This is all i have been provided. If it helps assume F is $0.$ k$1=$k$2=19\mathrm{.}4$kN$/$m and m$1=$ m$2=3$kg$.$ Task

You have a characterized two degree of freedom sys$-$

tem. The most important values are the mass $(m=$

$3$ kg $)$ and the spring stiffness $(k=19,4k\frac{N}{m}).$ You

have been asked to predict the dynamic response of

the two masses connected with identical springs. The

aim of this practical is again to investigate the accu$-$

racy of the mathematical model. You are required

to hand this completed sheet in at the end of the

practical session.

Homework problems

Calculate the analytical natural frequencies and mode

shapes for the given system $($Figure $1)$ with the given

parameters and $k=19,4k\frac{N}{m}.$ Home$-$

work must be handed in the practical session.
