XYZ Inc. is considering buying a machine costing $120,000. There are two
options Machine A and Machine B. Machine A will generate net cash inflow of $
40,000, $ 30,000 & $ 30,000 in year 1, year 2 & year 3 respectively. Machine B
will generate net cash inflow of $ 50,000, $ 60,000 & $ 70,000 in year 1, year 2 &
year 3 respectively.
A. Determine the payback period of the two projects and based on the result of
your calculation which project should have to be accepted.
B. Determine the discounted payback period of the two projects and based on the
result of your calculation which project should have to be accepted. (Assume
the market interest rate is 10%)
C. Determine the Net present value of the two projects and based on the result of
your calculation which project should have to be accepted. (Assume the
market interest rate is 10%)
D. From the given investment proposal evaluation techniques which on is better?

How propellers work in engineering?
The physics concepts of a propeller is that a props generate the thrust force that pulls a machine into the air. It also has aerodynamic properties that spins the propeller.?æ?æ
Which simple machine consist of a wheel that spins freely on its axle?
pulley
How do we get energy from Hydropower?
Dams: Falling water spins turbines to generate electricity.Wave power: Ocean waves transfer their energy to moving machinery which generates electricity.Tidal power: Tidal water rushes through narrow channels turning electricity generators.
What is the basic purpose of a generator?
Basically to generate electricity of energy.
If an alternator supplies electricity to an electric motor that spins the alternator will it run forever?
Yes, you could connect these parts together and it would operate. But after awhile you will find that the batteries are running low and the will motor is run slower than initially. The answer to the specific question is "no - you could not do this to generate electricity endlessly". If you could, that would constitute a perpetual motion machine, and that is impossible to do, due to losses in energy conversion because nothing is perfectly efficient.
Why does the splitting of atom generate electricity?
Splitting of atoms, fission is what we call it, generates heat, which flashes water to steam, which spins turbines, which spins generators, which make electricity.
How can you generate water into electricity?
You don't. But you can use the weight of falling water to generate electricity. The water spins a turbine (a type of fan blade), and the spinning turbine turns an electric generator.
How do you power machinery with hydropower?
A paddle wheel or turbine is turned by the moving water (the kinetic energy). This can be connected by a system of gears, wheels or even pulleys to turn a machine. This was how grain was ground into flour. After electricity was understood, the water spins turbines which generate electricity, and this electricity is used to run machines.
What apparatus are needed to generate hydro-electricity?
Moving water (dams, rivers, tides) and turbines (like an electric motor in reverse) that will produce electricity when the moving water spins them round.
Is this true or false in a controlled nuclear chain reaction the energy released as heat can be used to generate electricity?
It is true. The heat can flash water to steam, which spins turbines, which generates electricity.
What is the use energy from tides?
Tidal energy is captured by using turbines. When the tide comes in or out the moving water spins turbines that generate energy or electricity.
How is wind use to generate electricity?
Wind energy is used to generate electricity in a manner similar to the way water is used for the same purpose. The wind turns the blades of a giant turbine, which looks like a big fan, and the turbine turns a shaft. When the shaft turns it spins a generator which causes it to make electricity.

How does fossil fuels generate electrical energy energy transfer diagram?
Well, fossil fuels are burned which heat boilers, this creates steam which spins turbinescreating electricity.
How are fossil fules used to generate electricity?
they are burnt, the heat from burning is used to turn water into steam, the steam is then piped through turbines, the turbines spin at high speeds, these are connected via a drive shaft (long pole) to a big magnet which spins to generate the electric
How could exercise be used to generate electricity?
Here mechanical energy converted to electrical energy . so u can design a machine so that upon exercising the machine rotates the magnet in a alternator thus generating electricity
How could the island generate electricity?
the island generate electricity from sae water
