what happens to cutting force as the following increase: a.Rake
angle b.Material shear strength c.Depth of cut Are your findings as
expected based on the theory of machining? Why or why not?
At mechanics of metal cutting,
I cannot understand the reason why the shear angle is smaller
when the cutting speed is slow.
can you explain this to me?
a) Why does the shear strength of beams without stirrups
increase when the aggregate size increases?
b) Describe a bond-splitting failure. Why do stirrups tend to
prevent bond-splitting failures?
c) Why is the “side cover” and “back cover” important when
designing hooks for rebars?
d) What is the kern of a footing?
What will be the shear force diagram and bending moment diagram
for this question if the P is 4.0kN instead of 3.6kN?

Thanks.
What is the difference between a stabilizing force and
dislocating force? At what angle of pull does the stabilizing force
become a dislocating force? Why? For full credit, draw the free
body diagrams and equations of force or moment to support your
answer.
The an article gives the following summary data on shear
strength (kip) for a sample of 3/8-in anchor bolts: n= 18, mean is
4.25, and a sample standard deviation of 1.3. Calculate a 95%
confidence interval for true average shear strength. Interpret your
finding.
2. Consider the following observations on shear strength (MPa)
of a joint bonded in a particular manner:
22.2
40.4
16.4
73.7
36.6
109.9
30.0
4.4
33.1
66.7
81.5
a. Calculate the value of the sample mean and median. Why is the
median so different from the mean? Explain. [3 points]
b. Calculate the sample standard deviation. [2 points]
c. Are the smallest and largest observations outliers? Justify
your answer with appropriate calculations. [5 points]
