An animal in our JunglePark application needs to check whether another animal is in its neighborhood (close to it). To implement this behavior, add isClose() method to the Animal base class and implement it. This method must have the following signature.

public boolean isClose(Animal otherAnimal, int range) { }

The isClose() method returns TRUE if otherAnimal is located within a range distance [0 .. range] around the current animal and FALSE otherwise.

Part B. The worm shaft shown in part a of the figure transmits 1.2 hp at 500 rev/min. A static force analysis gave the results shown in part b of the figure. Bearing A is to be an angular-contact ball bearing mounted to take the 555-lbf thrust load. The bearing at B is to take only the radial load, so a straight roller bearing will be employed. Use an application factor of 1.3, a desired life of 30 kh, and a reliability goal, combined, of 0.90. Specify each bearing.

design and develop a miniature cryocooler in FORTRAN 77 software and validate it's result with EES AND fluent......

everything is well defined dont worry...you can skip it....

1. Answer the following question.
   • Describe an electro-mechanical machine. How do the systems work together to achieve a common goal?

Consider a clocked synchronous state machine with two inputs, A and B, and a single output Z that is 1 if

(1) A had the “same” value at each of the “three“ previous clock ticks, or

(2) B has been 1 since the last time that the first condition was true.

Otherwise, the output should be 0.

* Find the state/output table with the minimum state for this machine and draw the state diagram.

            For the metal matric composite above, determine the specific stiffnesses under (a) longitudinal and (b) transverse loadings. The fiber and matrix specific gravities are 8.29 and 6.08. Report the result in GPa.                                     For the metal matric composite above, determine the specific stiffnesses under (a) longitudinal and (b) transverse loadings.

saturated humid air at 1 atmosphere and 10 degrees Celsius is to be mixed with atmospheric air at 1 atmosphere, 32 degrees Celsius and 80 percent relative humidity, to form air of 70 percent relative humidity.
determine,
the proportions at which these two streams are to be mixed and the temperature of the resulting air

The piping system that delivers water to the second floor of your house, at an elevation of 16 feet from the ground, consists of 22 feet of 0.75" ID (ID = Internal Diameter) pipe followed by 16 feet of 0.5" ID pipe.   Calculate the minimum pressure required at the beginning of the piping system, located on ground level, for delivering water with a flowrate of 2.7 gallons per minute at atmospheric pressure on the second floor. Consider only losses at the constriction and major losses. The piping is copper, and has roughness of “drawn tubing”.

Air (Cp = 1.005 kJ/kg · K) is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. Air enters the heat exchanger at 95 kPa and 20◦C at a rate of 0.90 kg/s. The combustion gases (Cp = 1.1 kJ/kg · K) enter at a rate of 1.1 kg/s and 150◦C. The product of the overall heat transfer coefficient and the heat transfer surface area is U A = 1200 W/K. Assuming both fluids to be unmixed, use the effectiveness-NTU method to determine

(a) the heat exchanger effectiveness,

(b) the rate of heat transfer, and

(c) the exit temperature of the exhaust gases.
