A brass rod 150.00 mm long and 5.00 mm in diameter extends horizontally from a casting at 200°C. The rod is in an air environment with T∞ =20°C and h=30 W/m2·K. What is the temperature of the rod 37.50, 75.00, and 150.00 mm from the casting?

write a VBA code to convert an arbitrary positive binary fractional number (0< number<1) to equivalent decimal number. the code should acquire the binary fraction number in the format"0.xxxxxx"from input box, then return the equivalent decimal number in a message box. in the code, you may need to use VBA function "mid(_,_,_)" to pick up a specific symbols or characters from a string. you can use below conversion as benchmark to verify and debug your code:

(0.1011)₂ = (0.6875)₁₀

Two cylinders of oxygen are connected to each other by a valve. The first tank is 50 liters in volume and contains oxygen at 27 °C and a pressure of 140.37 kPa, and the corresponding values for the other tank are 30 liters, 89 °C and 62.73 kPa. If the valve connecting the tanks is opened and the tanks are allowed to reach some equilibrium condition with the temperature being 50 °C. Answer the following: (a) the equilibrium pressure, (b) the heat transfer between both tanks and the surroundings and the direction of the heat transfer, and (c) the internal energy in the final state if the tanks were insulated.

if f1=600N and theta=30°, determine the magnitude of the resultant force acting on the eyebolt and its direction measured clockwise from positive x axis

Conventional thinking in product development has been that innovation starts in advanced
developed countries like the United States and Japan. Products marketed in
countries where the average income is much lower often are older models of U.S. products
or used but still serviceable equipment. Several U.S. multinational companies have
established R&D labs in India and China. Originally this was to take advantage of the
large number of well-educated engineers who could be employed at salaries much lower
than the going U.S. rate, but soon it was found that these engineers were adept at developing
products for sale to the mass markets in these local countries. Typically these are
products with somewhat reduced functionality, but they still are useful quality products.
Now these U.S. companies are beginning to market these products in the United States
as a low-cost product line that is attractive to a new low-end market segment.
Search the business literature for examples of this new approach to trickle-up product
innovation. Discuss advantages of this new approach to product development and discuss
possible risks.

Compare oxy-fuel, plasma and laser cutting with respect to maximum temperature reached, materials that can be cut, kerf width, and tolerances.

A manufacturing operation requires 50 fc on the workplane in a 100 ft x 150 ft facility. The walls and ceilings are painted white. The work plane is 25 feet below the lights.

1. Calculate how many high-bay 400-W metal halide fixtures are required

2. Calculate how many 6-lamp T8 HBF fixtures are required.

. A steam main (outside diameter of 16.8 cm and inside diameter of 15.4 cm) is covered with 5-cm of high temperature insulation (k = 0.095 W/m. K) and 3.8 cm of lower temperature insulation (k = 0.07W/m. K). Calculate the heat loss from 150 m pipe assuming that inner and outer surface temperatures of the insulation are 450 and 30 °C, respectively. Also determine the temperature at the interface between two layers of insulation (10 points).

For H₂O, determine the specified property at the indicated state.

(a) T = 140°C, v = 0.5 m³/kg. Find p, in bar.
(b) p = 30 MPa, T = 120°C. Find v, in m³/kg.
(c) p = 10 MPa, T = 450°C. Find v, in m³/kg.
(d) T = 80°C, x = 0.8. Find p, in bar, and v, in m³/kg.

The surface energy of a single crystal depends on crystallographic orientation. Does this surface energy increase or decrease with an increase in planar density? Why? (Hint: Read “External Surface” part in S.4.6: Surface energy is proportional to the number of unsatisfied bonds of surface atoms)

please clear hand writing, also plesae don't give me the book answer.

Thank you.

Find one example of a product where the largest or most detrimental environmental impact persumably derived from each of the following:

1. Raw Material Acquisition

2. Production

3. Consumption

 4. Disposal

One integrated circuit design calls for the diffusion of arsenic into silicon wafers; the background concentration of As in Si is 2.5 × 1020 atoms/m3. The predeposition heat treatment is to be conducted at 1000°C for 45 minutes, with a constant surface concentration of 8 × 1026 As atoms/m3. At a drive-in temperature of 1100°C, determine the diffusion time required for a junction depth of 1.2 μm. For this system, values of Qd and D0 are 4.10 eV and 2.29 × 10−3 m2/s, respectively. (The answer is NOT 49.12hours)

Leaf springs are commonly used in low-cost or high-stiffness vehicle suspensions, e.g. golf cars, light-truck rear axle. Consider a cold-drawn AISI 1040 flat leaf spring subjected to a fluctuating loading condition of maximum and minimum stresses of 420 MPa and 140 MPa respectively for a total of 50,000 cycles. The loading condition of the spring then changes to maximum and minimum stresses of 350 MPa and -200 MPa respectively. Estimate the remaining life of the spring under the new loading condition using Palmgren-Miner cumulative damage theory. Assume that the fully-corrected endurance limit is 200 MPa and Sn is 90% of Sut.

As mechanical engineering explain the reason why an early airbag was a failure, and the reason any system acquisition processes that were not followed that may have contributed to the failure.
