Textbook Question
Chapter 15, Problem 8RQ
You are studying the effects of climate change on the Arctic ice sheet. You have collected data at several locations on different dates. The data is stored in the matrix Ice. Each row of Ice contains the measurements made on a specific date. Each column of Ice contains the measurements made at a specific location. You may assume that Ice contains at least two rows and at least two columns, but may be considerably larger in either or both dimensions. As part of analyzing this data, write a single MATLAB command to achieve each goal below. The results from each step may be used in subsequent steps as necessary. HINT: Use help or doc to learn more about the functions mean and min.
a. Place the number of rows in Ice in the variable Dates and the number of columns in Ice in the variable Locs.
b. Add another row at the bottom of Ice that contains the averages of the values (ice thicknesses) in the corresponding columns.
c. Add another column on the right side of the modified matrix Ice that contains the averages of the values (ice thicknesses) in the corresponding rows. Note that after this step, the lower right corner value will be an overall average of all data in the original matrix.
d. Add another column on the right side of the modified matrix Ice that contains the minimum of the values (ice thicknesses) in the corresponding rows. Note that after this step, the lower right corner value will be the minimum of the average values that were added as a new bottom row in the second step above.

As we explained in earlier chapters, the
air resistance to the motion of a vehicle
is something important that engineers
investigate. The drag force acting on a
car is determined experimentally by
placing the car in a wind tunnel. The air
speed inside the tunnel is changed, and
the drag force acting on the car is
measured. For a given car, the experimental
data generally is represented by a
single coefficient that is called drag
coefficient. It is defined by the following
relationship:
F,
where
air resistance for a car that has a listed
C, = drag coefficient (unitless)
measured drag force (N)
drag coefficient of 0.4 and width of 190 cm
and height of 145 cm. Vary the air speed
in the range of 15 m/s
You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…

The lens will create a virtual image of a distant object at the far point (the farthest an object can be from the eye and still be in focus) of the myopic viewer where it will be clearly seen. In the traditional treatment of myopia, an object at infinity is focused to the far point of the eye. If an individual has a far point of 39.5 cm, prescribe the correct power of the lens that is needed. Assume that the distance from the eye to the lens is negligible.arrow_forward
