For the bar shown in Figure P16–8, determine the nodal
displacements, velocities, and accelerations for five time steps using two
finite elements. For simplicity of calculations, let E = 1

1. For the beams shown in Figure P16–11, determine the
natural frequencies using first two and then three elements. Let E; r, and A be
constant for the beams.

1. For the beams in Figures P16–13 and P16–14 subjected to
the forcing functions shown, determine the maximum deflections, velocities, and
accelerations. Use a computer program.
2. For the rigid frames in Figures P16–15 and P16–16
subjected to the forcing functions shown, determine the maximum displacements,
velocities, and accelerations. Use a computer program.

,
and c = 800 W s/(kg C) is 2 cm thick and at an initial uniform temperature of
Ti = 200 C. The left surface is suddenly lowered to 0 C and is maintained at
that temperature while the other surface is kept insulated. Determine the
temperature distribution in the slab for 40 s. Use b = 2 3 and a time step of 8
s.

A circular fin is made of pure copper with a thermal
conductivity of k = 400 W/(m C), h = 150 W/(m
2
C), mass density r =
8900 kg/m

, and specific heat c = 375 J/(kg C). The initial
temperature of the fin is 25 C. The fin length is 2 cm and the diameter is 0.4
cm. The right tip of the fin is insulated. See Figure P16–18. The base of the
fin is then suddenly increased to a temperature of 85 C and maintained at this
temperature. Use the lumped form of the capacitance matrix, a time step of 0.1
s, and b =2 3. Use two elements of equal length. Determine the temperature
distribution up to 3 s. Compare your results with Example 16.7, which used the
consistent form of the capacitance matrix.

Why it is important to include considerations for security and privacy in an EA program and within the documentation of EA components? What are the implications to EA of incorporating third party vendors into the design and architecture?
