= iL/N for i = 1, 2, . . . , N. Formulate the principle of virtual
work for this system assuming that R(0) = 0
Results obtained from a tension test on a bar of
uniform cross section 10 mm x 10 mm subjected to an axial pull of
8000 N were tabulated. The lateral dimensions of the bar were found
to be changed to 9.9985 mm x 9.9985 mm while using a material
having modulus of rigidity equal to 0.8 x 107 N/cm2. By determining
the values for different moduli, identify the properties of
material and establish the relationship between them. What changes

Compression of a bit string x of length n involves creating a
program shorter than n bits that returns
x. The Kolmogorov complexity of a string K(x) is the length of
shortest program that returns x (i.e.
the length of a maximally compressed version of x).
(a) Explain why "the smallest positive integer not definable in
under 100 characters" is paradoxical.
(b) Prove that for any length n, there must be at least one bit
string that cannot be compressed...
When subjected to a force of compression, the length of a bone
(compression Young's modulus 9.4 x 109 N/m2,
tensile Young's modulus 1.6 x 1010 N/m2)
decreases by 2.7 x 10-5 m. When this same bone is
subjected to a tensile force of the same magnitude, by how much
does it stretch?Type your question here
If X-bar= 95, S = 22, and n = 64, and assuming that the
population is normally distributed,
a. Construct a 99% confidence interval for the population mean,
μ.
b. Based on your answer to part (a), test the null hypothesis
that the population mean μ = 101 vs. the alternative that μ ≠
101.
c. What is the probability that μ = 101? d. What is the
probability that μ > 101?
