Three linear elastic coil springs are symmetrically arranged
asshown below. for the two identical springs on the outside,
thestiffness coefficient is equal to k, whereas the spring in
themiddle has a stiffness coefficient equal to 2k. the system
isinitially subjected to an external force p0, of
which40% is carried by the spring in the middle while the balance
iscarried equally by the outside springs. subsequently, the
externalforce was increased to p. compute: a) the new values fo the
springforces b) the toal deformation energy stored in
thesystem.
