Case Study: Anglo American PLC in South Africa.
Anglo American PLC in South Africa: What do you do when costs reach epidemic proportions?
Please read the case study carefully and respond to the following:
Research the current budget and policies of the South African government on dealing with the epidemic. How are they currently handling the issue?
Discuss the pros and cons of the pharmaceutical industry assisting the South African government in addressing the HIV/AIDS issue.
Do stakeholders have a moral responsibility to assist the South African government? Why or why not? -

Create 3 lesson plans
: A planned series of literacy learning experiences (with analysis/justification) appropriate for the early years of school which demonstrate an understanding of contemporary theories and pedagogy and familiarity with quality children’s literature.
Note: digital or multimodal communications need to be included in the portfolio.
(this can be included as an alternative activity for children with additional needs or it could be for one of the three lesson plans)

a. Obtain the global stiffness matrix =K of the assemblage
shown in Figure P2–1 by superimposing the stiffness matrices of the individual
springs. Here k

, and k3 are the stiffnesses of the
springs as shown.
b. If nodes 1 and 2 are fixed and a force P acts on node 4
in the positive x direction, find an expression for the displacements of nodes
3 and 4.
c. Determine the reaction forces at nodes 1 and 2.
(Hint: Do this problem by writing the nodal equilibrium
equations and then making use of the force/displacement relationships for each
element as done in the first part of Section 2.4. Then solve the problem by the
direct stiffness method.) -

1. For the spring assemblage in Figure P2–5, apply a
concentrated force of 2 kips at node 2 in the positive x direction and
determine the displacements at nodes 2 and 4.
2. Instead of assuming a tension element as in Figure P2–3,
now assume a compression element. That is, apply compressive forces to the
spring element and derive the stiffness matrix.
