- Power Equipment
- Planning/Design
Metal Fabrication
The ability to accomplish a task with a minimum amount of energy, time, and waste.
Efficiency
What do you do during the "Test and Redesign" phase of the engineering process?
Test the original prototype and see what adjustments need to be made, then make the needed adjustments.
Give me an example of Chemical Energy that deals with livestock.
Cows eat their feed, feed gives them nutrients, and the nutrients are stored to be used as energy.
weight (newtons) = mass × 9.8 meters/second2
Mass: .483 kg
4.73 Newtons
Global Positioning Systems (GPS) and Geographic Information Systems (GIS) used to map fields, determine input costs, and calculate yields.
- Sustainable Energy
- Planning/Design
-Precision Agriculture
Precision Agriculture
Any instrument used in doing work.
Tool
How do you use prototypes in the engineering design process?
You create a prototype that will solve your problem to test and make adjustments to see what works most efficiently.
How does a machine lose energy as it is transferred from one form into another?
Thermal Energy, creates heat and the heat is released.
power (watts) = work (joules) / time (seconds)
300 Joules
45 Seconds
6.67 Watts
The designing and improvement of structures and equipment using an engineering process.
- Construction
- Planning/Design
-Power Equipment
Planning/Design
This unit of measurement created to measure power of an engine in relation to a certain animal.
Horsepower
Explain what happens during the "Communicate Results" Step
Communicate with who will be using your product. Get feedback on design, and use it to help redesign
List 3 Forms of Kinetic Energy
Electrical, Mechanical, Thermal, Gravitational, Sound, Light
horsepower = (distance x weight )/ (time x 33,000 foot pounds)
2500 lbs
500 feet
5 minutes
7.575 Horsepower
Design and build structures to store and raise agricultural commodities.
- Construction
- Planning/Design
- Concrete/Masonary
Construction
A unit of power that measures the rate at which energy is used, produced, or transferred. Use with electricity
Watt
How is the engineering design process used to improve agricultural production?
Problems are defined, engineers research and develop a solution which they test and redesign as needed. This is communicated with others who suggest changes and give feedback.
Define Kinetic & Potential Energy
Kinetic: Being used currently
Potential: Stored
power (watts) = work (joules) / time (seconds)
Joules: 250
Time: 200 seconds
1.25 watts
Using liquids and gases under pressure to lift heavy objects and power motors.
