Answer:

Prosthetics come from the minds of biomedical engineers. They start their projects by consulting with managers, medical professionals and patients. They create initial designs on computer, before developing a prototype that they can test for safety and effectiveness. Several rounds of testing and modification may be necessary before they produce the final prosthetic.QualificationsStudents interested in biomedical engineering begin their education with high-school courses in biology, physics, mathematics, drafting and computers. They continue with a bachelor’s degree in biomedical engineering from an accredited institution. Columbia University offers a typical program of study. The first two years cover general education courses in English, physical education, humanities, math, physics and chemistry. The last two years focus on the engineering specialty, such as biomechanics, which include experiences in the classroom and laboratory. Internships and co-ops, such as with hospitals, can provide the practical experience valued by employers.

zloy xaker [14]

Answer:

E) Please see below as the answer is self -explanatory.

Explanation:

The pareto chart, is used in quality control, and is a combined type of graph, that uses a line-type curve to denote the cumulative percentages of the different types of defects found in a sample (so the maximum value is 100%)

Also, it features a bar chart, which shows the relative occurrence of the different values (as in a histogram) which allows to find easily which defects are more relevant ones, alerting in this way about unacceptable deviations in the manufacturing process (if we are producing a good under given quality standards, for instance).

Determine the design angle ϕ (0∘≤ϕ≤90 ∘) between struts AB and AC so that the 400 lb horizontal force has a component of 600 lb

Svetllana [295]

Answer:

design angle ∅ = 4.9968 ≈ 5⁰

Explanation:

First calculate the force Fac :

Fac = $\sqrt{400^2 + 650^2 - 2(400)(650)cos30}$

= $\sqrt{160000 + 422500 - 80210}$

= 708.72 Ib

using the sine law to determine the design angle

$\frac{sin}{400} = \frac{sin 30}{Fac}$

hence ∅ = $sin^{-1} (\frac{sin 30 *400}{708.72} )$

= $sin^{-1} 0.0871$ = 4.9968 ≈ 5⁰

For a very rough pipe wall the friction factor is constant at high Reynolds numbers. For a length L1 the pressure drop over the

Goshia [24]

Answer:

$\Delta p_{2} = 2\cdot \Delta p_{1}$

Explanation:

The pressure drop is directly proportional to the length of the pipe. Then, the new pressure drop is two time the previous one.

$\Delta p_{2} = 2\cdot \Delta p_{1}$
