A pin-connected linkage bar is 16 in. long and is subjected to an axial compressive load of 4600 lb. The bar is made of a high-strength steel with a yield stress of 110,000 psi.
Compute the required dimensions of the bar if its cross section is to be rectangular with the width being twice the depth. Use the Euler-Johnson formulas with a factor of safety of 3.0.
Draw the qualitative influence line for the moment at B - compute the maximum moment at B.
Three return steam lines in a chemical processing plant enter a collection tank operating at steady state at 1 bar. Steam enters inlet 1 with flow rate of 0.8 kg/s at 200 C. Steam enters inlet 3 with flow rate of 1.2 kg/s at 95 C. Steam exits the tan..
Pure chlorobenzene is contained in a flask attached to an open-end mercury manometer. When the flask contents are at 58.3°C, the height of the mercury in the arm of the manometer connected to the flask is 747 mm, and that in the arm open to the atmos..
A shaft is subjected to mean torque of 3 * 10^6 n. mm superimposed with variable torque of 3 * 10^6 n. mm. It is also subjected to bending moment of mean zero and a superimposed variable of 6 ^ 10^6 n. mm. Design the shaft to support the load for an ..
Consider a 2 mm thick silicon wafer to doped using antimony (Sb). Assume that the dopant source (gas mixture of Antimony Chloride and other gases) provides a constant surface concentration of 6.4*10^22 atoms/m3. A heat treatment is desired such that ..
A 2-D reducing bend (of unit width w) is shown below. Note that flow enters the bend at section 1 with a linear velocity profile, but at sections 2 and 3 is uniform. Find the velocity at section 3.
A turning operation uses a 2/64 in nose radius cutting tool on a free machining steel with a feed rate = 0.010 in/rev and a cutting speed = 300 ft/min. Determine the surface roughness for this cut.

a ceramic has k0.8 wmk. if this ceramic is shaped into a cylinder with a porosity distribution given by p.1xl1-xl where
I want a brief report on "Micro Heat Pipes". (It should cover What are Micro heat pipes, where they are used, why they are used, advantages, disadvantages, applications, any changes/improvements to be made, future of these micro heat pipes.
a cylinder fitted with a piston contains 10 lbm of r-134a at 100 psia and 140 degree f. the refrigerant is cooled at
Show that the specific heat at saturation of a liquid phase of mass m (defined by Cf= (deltaQ/m)dt is generally not the same as the specific heat at constant pressure of the saturated liquid.
