A slab of intrinsic GaAs, 3cm long, 2cm wide, and 0.3cm thick, is exposed to light. The light is absorbed with an absorption coefficient a=500cm1 (this means that the light intensity decreases in the

1.) Answer the following questions. a.) Briefly describe the problem resulting from the overaging of a precipitation hardened alloy. b.) At what temperature does a 5.0wt% CuAl alloy completely solidi

Briefly describe the simplest heat treatment procedure that would be used in converting a 0.76 wt% C steel from one microstructure to the other, as follows: Pearlite to tempered martensite heat to a

A vibratory system with a moving base has a mass of 300 kg, a spring with a stiffness of 40000 N/m and a damper with an unknown damping constant. It is observed that the mass vibrates with an amplitud

Consider the mechanical system shown in the Figure below. In the diagram, the displacements x and y are measured from their respective equilibrium position. Assume that m = 1 kg M = 10 kg k1 = 10 N/m

An aluminum alloy has a yield strength y=150MPa. A component made from this alloy is subjected to x=200MPa and y=50MPa, with all other stresses equal to zero. Calculate the equivalent stress. Does

these resistors, 10 ,15 and 20 , are connected in series across a (+, ) . What is the total voltage that drop across the resistor (15 ) , 12?

A wind turbine with a diameter of 100 ft operates during a 24h period in which the wind velocity may be approximated by half a sine wave as V(theta)=V(m)sin(pi*theta/24), where theta is time in hours

A 3092 lbf vehicle is traveling at 200 ft/sec when a constant braking force of 766 lbf is applied. The vehicle has a large frontal area and aerodynamic drag cannot be neglected from the braking equati

Tips for Asking Questions
 Provide any and all relevant background materials. Attach any necessary files to ensure your Tutor has all the required information to answer your question as completely as possible.
 Set a compelling price. While our Tutors are eager to answer your questions, offering a compelling price speeds up the process by avoiding any unnecessary price negotiations.
Sample Questions
 A closed, rigid tank whose volume is 1.5 m3 contains refrigerant 134a, initially a two phase liquidvapor mixture at 10C. The refrigerant is heated to a final state where temperature is 50C and quality is 100%. Locate the initial and final states on a sketch of the Tv digram. Determine the mass of vapor present at the initial and final state, each in kg.
