A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.
What is in a lens?
Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.
Who can create a lens?
Any individual member, a community, or a respected organization.
What are tags?
Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
This content is either by members of the organizations listed or about topics related to the organizations listed. Click each link to see a list of all content affiliated with the organization.
If you have permission to edit this content, using the "Reuse / Edit" action will allow you to check the content out into your Personal Workspace or
a shared Workgroup and then make your edits.
Derive a copy
If you don't have permission to edit the content, you can still use "Reuse / Edit" to adapt the content
by creating a derived copy of it and then editing and publishing the copy.

'My Favorites' is a special kind of lens which you can use to bookmark modules and
collections. 'My Favorites' can only be seen by you, and collections
saved in 'My Favorites' can remember the last module you were on. You need an account
to use 'My Favorites'.
(i) Derive the AA and KK
matrices resulting from the removal of the fourth
spring,
(ii) Compute the inverse, by hand via
Gauss-Jordan, of the resulting
ATKAAKA
with
k1=k2=k3=kk1k2k3k
(iii) Use the result of (ii) to find the displacement
corresponding to the load
f=00FTf00F.
Exercise 2
Generalize example 3,
the general planar truss, to the case of 16 nodes
connected by 42 fibers. Introduce one stiff (say
k=100k100)
fiber and show how to detect it by 'properly' choosing
ff. Submit your
well-documented M-file as well as the plots, similar to
the before-after
plot in the general planar module, from which you
conclude the presence of a stiff fiber.
