Product Design and Development (6th Edition)

Develop several concept sketches for a common product. Try designing the product form both “from the inside out” and “from the outside in.” Which is easier for you? Possible simple products include a stapler, a garlic press, an alarm clock, a reading light, and a telephone

Design a muff coupling to connect two shafts transmitting 40 kW at 120 r.p.m. The permissible shear
and crushing stress for the shaft and key material (mild steel) are 30 MPa and 80 MPa respectively.
The material of muff is cast iron with permissible shear stress of 15 MPa. Assume that the maximum
torque transmitted is 25 per cent greater than the mean torque.

A long cylindrical object with diameter D=100cm (k=400 W/mK, C­_p = 400 J/kg K, density = 9000 kg/m³) is put into an oven of 1100 K with convective

heat transfer coefficient h of 50 W/m² K. The initial temperature of this object is 300 K. How much time does it take for the center of the object to reach

700K? How much time does it take for the surface of the object to reach 700K?

consider the IVP ( cos(x)sin(x) - xy^2)dx + (1-x^2)ydy = 0 , y(0) = 34

solve the IVP

answer))) 1156 = ???

What is the best mechanical pencil lead size (i.e. 0.5, 0.7 etc) and lead type (I.e. Hb etc) for engineering drawing (isometric and orthogonal) ?

Hydrolevel vs. ASME case study

What can engineering societies do to defend their goods once a conflict of interest is exposed?

Have ASME's reviewed conflict-of-interest procedures addressed the difficulties fully? Why or why not?

A = 5kN@40*
B = 10kN@140*
C = 25kN@240*

In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. A certain recirculating loop involves 300-foot-long, 1-inch--diameter PEX pipes with six 90° threaded smooth bends and two fully open gate valves. The PEX piping is considered to be smooth (roughness is 0). If the average flow velocity through the loop is 5 ft/s, determine the pump power needed to overcome the loss in watts to three significant figures. Take the average water temperature to be 180 F (values for water in the text appendix).
