Engineer Doe is employed on a full-time basis by a radio broadcast equipment manufacturer as a sales representative. In addition, Doe performs consulting engineering services to organizations in the radio broadcast field, including analysis of their technical problems and, when required, recommendation of certain radio broadcast equipment as may be needed. Doe’s engineering reports to his clients are prepared in form for filing with the appropriate governmental body having jurisdiction over radio broadcast facilities. In some cases Doe’s engineering reports recommend the use of broadcast equipment manufactured by his employer. Can Doe ethically provide consulting services as described? What NSPE Code of Ethics references might apply to this case? |

The propeller shaft of a large ship has an outside diameter of 350 mm and inside diameter 250mm. the shaft is rated for a maximum of shear stress 62 MPa.
1) if the shaft is runnning at 500 rpm what is the maximum power that can be transmitted without exceeding allowable stress.
2) if the rotational speed of the shaft is doubled but the power requirements unchanged what happens to the shear stress in the shaft? calculate valures.

Heat is generated uniformly at a rate of 2x105
W/m3 in a wall of thermal
conductivity 25W/m K and thickness 60 mm. The wall is exposed to
convection
on both sides, with a fluid temperature of 30C and h =
50W/m2 K
on the left side, a fluid temperature of 15C and h = 12
W/m2 K on the
right side.
(a) Determine surface temperature on each side of the wall,
and
(b) the maximum temperature in the wall.

As changes across industries driven by Process, People, Technology happen at a rapid pace. The quality management toolkit needs new relevance. The basic principles of Quality Management are still relevant in the 21st century. With examples, outline how enterprises are applying the QM principles such as 1) Drive out fear, so that everyone may work effectively for the Enterprise, 2) Respond quickly to employee feedback and implement corrections, 3) Break down barriers between departments and work as a team and 4) Quality is meeting the needs of the customer. Discuss how Data, Process and People are being leveraged for this purpose.

Write MATLAB scripts to solve problem 5.21 from the textbook (bisection, specific heat) four times:
a) with the bisection method (starting interval [0, 1200])
b) with the false-position method (starting interval [0, 1200])
c) with the Newton-Raphson method (x0 = 0)
d) with the secant method ((x0, x1) = (0, 1))
use percent relative error = 10^-6 as stopping criterion.
5.21-Mechanical engineers, as well as most other engineers, use thermodynamics extensively in their work. The following polynomial can be used to relate the zero-pressure specific heat of dry air cp kJ/(kg K) to temperature (K):
cp = 0.99403 + 1.671 × 10?4T + 9.7215 × 10?8T2 ?9.5838 × 10?11T3 + 1.9520 × 10?14T 4
Develop a plot of cp versus a range of T = 0 to 1200 K, and then determine the temperature that corresponds to a specific heat of 1.1 kJ/(kg K).
