Question 1

- The designers should have the
knowledge of the analytical design
process which is essential in the design
of machine components, main frames,
mounting arrangement, balancing, etc.
- The designers must integrate analytical
design and results of experimental
investigation to develop machines that
are simple to fabricate, affordable, light
in weights, easy to maintain, and
require readily available and low cost
materials.
- The designer should also have the
knowledge regarding the level of
manufacturing skills, processes,
viability, and cost of materials in order
to have a simple machines that could
be locally manufactured.
- The design of agricultural machines
should involved a multi-disciplinary
approach that involves product design,
development, testing and evaluation,
and modification prior to
commercialization.
