Answer:
Problem 1.5
Find the relationship between the thickness t and the length l for a
microcantilever such that the stiffness ratio at the free end 1 is
equal to n (n > 1), and that the axial stiffness at the same point is less than a
fixed value of
Answer:
Problem 1.6

has a radius of Determine the position of the neutral axis
by calculating the eccentricity e.
Answer:
for 0.6 < R/w < 8
for R/w > 8
relative error between the first and second predictions: 0.1%
