A three phase source supplies a building with 18 KV which has a group of four 3-phase loads as follows:

LOAD 1: Wye connected; S=444 KVA and 0.84 lagging power factor

LOAD 2: Delta connected; S=693.75 KVA and 0.64 leading power factor

LOAD 3: Wye connected; Z= 140 + j240 Ω

LOAD 4: Unbalanced wye-connected and grounded load, with  Za = 14+j3 Ω , Zb = 5-j24Ω and Zc =1+j14 Ω

Conservation of Angular Momentum

A female figure skater is spinning on ice. Assume that that the surface is basically frictionless. The skater is wearing weighted bracelets as part of the costume for the performance. These weighted bracelets weight .75 kg each. The skater has a spinning routine in the middle of the performance and initially starts spinning with arms stretched wide such that the weighted bracelets are 1 m from the axis of rotation. She has an initial angular velocity of 2LaTeX: \pi π rad/s with an initial moment of inertia of 2.5 kg * m2. The skater then pulls her arms in towards her chest so that the weighted bracelets are just 10 cm from the axis of rotation as this will allow a faster spin, her moment of inertia drops to 2.1 kg * m2.

Part 1. What is the initial angular velocity of this skater. (answer should be a whole number)

rev/s

Part 2. What is the initial kinetic energy the skater has? (give your answer to the nearest J)

J

Part 3. What is the final angular velocity of this skater. (give your answer to 3 significant digits)

rev/s

Part 4. What is the final kinetic energy the skater has? (give your answer to the nearest J)

J

The following class keeps track of how many flavors are at an ice-cream place, and the number of calories of each flavor. The calories of each flavor ice-cream are positive values of type unsigned int and are stored as a dynamically allocated array. The first data member is a pointer that will point to the first element of the array. This array will be of an arbitrary size. The default size of the array shall be 25, but may be specified by the user at the time of construction. The second data member represents the size of the array, i.e. the number of menu items, and is stored as size_t.

class IcrecreamCalories {
private:
unsigned int* calories;
size_t num;
public:
// constructors (default, one arg, and copy)
IcecreamCalories();
IcecreamCalories( unsigned int numberOfFlavors);
IcecreamCalories( const IcecreamCalories& original);
// destructor
~IcecreamCalories();
// Member function
int calorieAtIndex( int index );
};

Please answer the following two questions, typing the item number before each answer:

i) Why MUST the parameter of the copy constructor be of type constant reference?

ii) If this is in the Class Specification (header) file IcecreamCalories.hpp, write the function definitions that would be in the Class Implementation (source) file IcecreamCalories.cpp.

One year​ ago, your company purchased a machine used in manufacturing for $ 120,000. You have learned that a new machine is available that offers many​ advantages; you can purchase it for $ 140,000 today. It will be depreciated on a​ straight-line basis over ten​ years, after which it has no salvage value. You expect that the new machine will contribute EBITDA​ (earnings before​ interest, taxes,​ depreciation, and​ amortization) of $ 55,000 per year for the next ten years. The current machine is expected to produce EBITDA of $ 23,000 per year. The current machine is being depreciated on a​ straight-line basis over a useful life of 11​ years, after which it will have no salvage​ value, so depreciation expense for the current machine is $ 10,909 per year. All other expenses of the two machines are identical. The market value today of the current machine is $ 50,000. Your​ company's tax rate is 40 %​, and the opportunity cost of capital for this type of equipment is 12 %. Is it profitable to replace the​ year-old machine?
