technology and livelihood education
industrial arts for grade seven quarter
4 week three part two our topic is power tools
the content standard for this lesson is
the Learners demonstrate an
understanding of the concepts in
Services the performance standard is the
Learners perform mensuration and
precautions here are the learning
competency and learning objectives for
review of the previous lesson name the
vocabulary power tools are electrically
or battery operated devices used to
perform various tasks such as cutting
drilling grinding or sanding they
increase efficiency and Precision in
tasks that would otherwise require
manual effort and are commonly used in
maintenance pneumatic tools are powered
by compressed air making them efficient
for heavy duty tasks in Industries like
construction automotive and
Manufacturing these tools include drills
impact wrenches Sanders and grinders
offering high torque and precision they
are durable lightweight and reduce
operator fatigue compared to manual or Electric
Tools hydraulic tools use pressurized
fluid to generate Force providing
powerful and precise performance common
in construction automotive and
Industrial applications they include
Jacks presses and Cutters these tools
offer high efficiency torque and
tools the power tools most modern
construction or manufacturing
applications will likely utilize one or
a combination of two power sources
hydraulic and pneumatic the distinction
between pneumatics and hydraulics is
based on the medium used for power
transmission pneumatics rely on
compressible Gases such as air or pure
gas at the same time Hydraulics use
incompressible liquids like mineral oil
ethylene glycol water synthetic fluids
or high temperature resistant fluids to
transmission comparison of hydraulic and
pneumatic power system pressurized air
air or gases are utilized in pneumatics
to provide fluid power while Hydraulics
rely on pressurized liquids like oil or
water when deciding between the two
factors such as cost Effectiveness the
nature of the materials to be moved
resource availability and space
constraints must all be considered for
instance heavy lifting equipment
occupies significant space and demands
substantial power unlike the smaller
scale requirements of robotic laboratory
or food processing equipment it is
important to note that each power type
has advantages and disadvantages
circumstances health and safety
considerations for pneumatic and
hydraulic tools pneumatic and hydraulic
tools like any other equipment have
advantages and disadvantages regarding
health and safety while they may reduce
specific hazards they also introduce new
ones hence it is crucial to carefully
choose the appropriate tools for each
task to identify and address the
associated risks this selection process
should be integral to the risk
assessment and control procedure
ensuring that the tools are
wellmaintained and operated by competent
individuals and following the
manufacturer's instructions is essential
additionally these tools share similar
hazards with other tools powered by
electricity the following are the common pneumatic
