Ag Mechanic Basics
What is agricultural mechanics?
The use of mechanical skills and technology to support agricultural production and processing.
What is energy?
The ability to do work.
What makes a machine efficient?
It performs maximum work with minimum energy loss.
What is the engineering design process?
A series of steps used to solve problems and develop new technologies.
What is a driveshaft?
A rotating shaft that transmits power from an engine to a machine part.
Why are the terms agricultural mechanics and agricultural power and technology used interchangeably?
Because both describe the application of mechanical and technical systems in agriculture.
What are two main forms of energy used in agriculture?
Renewable and nonrenewable energy.
How do you measure efficiency?
(Useful output ÷ total input) × 100%.
What is a prototype?
A working model built to test a design idea.
Define kinetic energy.
Energy of motion.
What is the purpose of a tool?
To extend human ability and make work easier or more efficient.
How is power different from work?
Work is the amount of energy used; power is the rate at which work is done.
What is the difference between SI and English measurements of power?
SI uses watts; English uses horsepower.
How do engineers use prototypes?
To evaluate and improve their designs before final production.
What is a hydraulic system?
A system that uses liquid under pressure to transmit power.
How can you use mechanical systems in agriculture?
To plant, harvest, transport, process, and maintain agricultural products and equipment.
What is the standard unit of power?
Watt (W)
How many watts are in one horsepower?
746 watts.
How is the design process used in agriculture?
It helps create more efficient machines, tools, and systems.
What is the engineering unit of force?
Newton (N).
What are examples of mechanical systems used in agriculture?
Irrigation, hydraulic, pneumatic, electrical, and structural systems.
What is one way machines convert energy into usable forms?
Engines convert chemical energy into mechanical energy.
What factors determine how much power a machine produces?
Force applied, distance moved, and time taken.
What are the major components of the design process?
Define the problem, research, brainstorm, prototype, test, and improve.
What is a technical manual?
A reference document that explains how to operate, maintain, or repair equipment.
