Question deals with a leaning platform supported by three springs and a point loan on top. see file for specifics.

Given: Looking down on platform supported by three springs arranged in an isosceles triangle pattern. Spring constant for orange springs =k1. Spring constant for purple spring =k2.

Find: If a 350 lbs weight is put on platform at point shown, what will be the deﬂection in the Z direction at the
star? What will be the deﬂection at the purple spring?

See the attached file.
