To represent a location on earth surface you need to define its altitude and longitude
angles.

Solar zenith and solar incidence angles have the same value for horizontal surface.
At sunset time the value of solar altitude angle is maximum.

When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun
rays are reaching the receiving plane.
The solar irradiance and the solar irradiation have the same physical meaning.
In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less
than the diffused irradiation.
The total solar radiation received by a tilted surface is the same as that…

Question *
In an engineering department, the acceptance in the civil major and the
acceptance in the mechanical major are two independent events. However, it is
more likely to be accepted in the mechanical major. The probability to be
accepted in both majors is 0.012, however to be accepted in at least one major
is 0.208. Let “C" be the event the acceptance in the civil major and let "M" be the
event the acceptance in the mechanical major. Then:
O P(C)=0.02 and P(M)=0.6
P(C)=0.1 and P(M)=0.12
P(C)=0.06 and P(M)=0.2

please help solve A-F. thank you
You are an engineer working on a project and your prototype has failed prematurely. You question whether or not a key component of the prototype was manufactured with the correct material. There are two way to check for the material properties. The first way is to have a material certification done to confirm the exact material composition. This will take some time. The second method to confirm the material properties is to make an ASTM test sample and test for the material properties. This tensile test was completed on a test sample with an initial diameter of .501” and an initial length of 2”. The Load-Deflection data for this tensile test is below. Use this data to answer the first set of questions on the Final Exam in eLearning. A. Determine the Ultimate Tensile Strength B. Determine the 0.2% Offset Yield Strength C. Determine the value of the Proportional Limit D. Determine the Modulus of Elasticity E. Determine the Strain at Yield F. Calculate %…

Question 2
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…

Question 20 of 20 <
A Water Balloon Battle. You are launching water balloons at a rival team using a large slingshot. The other team is set up on the
opposite side of a flat-topped building that is 30.0 ft tall and 50.0 ft wide. Your reconnaissance team has reported that the opposition is
set up 10.0 m from the wall of the building. Your balloon launcher is calibrated for launch speeds that can reach as high as 100 mph at
angles between 0 and 85.0° from the horizontal. Since a direct shot is not possible (the opposing team is on the opposite side of the
building), you plan to splash the other team by making a balloon explode on the ground near them.
If your launcher is located 55.0 m from the building (opposite side as the opposing team), what should your launch velocity be ((a)
magnitude and (b) direction) to land a balloon 5.0 meters beyond the opposing team with maximum impact (i.e. maximum vertical
speed)?
