Wind Energy

Wind energy is a renewable energy source that is used to generate electricity by wind power. The term, wind power, means utilization of kinetic energy of wind to generate electricity. Wind energy is termed renewable source energy because it can never be exhausted. There are other renewable energy sources, such as solar energy, geothermal energy, hydropower energy, and so on. All of them contribute to power the thermal energy stations to generate electricity.

Chapter 7- DOZER PRODUCTION
A track-type dozer equipped with a power shift can push an average blade load of 6 lcy. The
material being pushed is silty sand. The average push distance is 88 ft. What production, in
loose cubic yards (Icy), can be expected?
Push time: 3 mph average speed (sandy material):
distance (ft)
Push time =
X 60min/hr = .

Return time: Second gear because less than 100 ft.
Maximum speed 5 mph:

The dozer must accelerate to attain the maximum velocity. Therefore, when using such speed
data, it is always necessary to make an allowance for acceleration time. Because, in this
example, the change in speed is very small, an allowance of 0.05 min is made for acceleration
time.
Return time =
