CHAPTER I
THE PROBLEM, ITS BACKGROUND AND REVIEW OF RELATED LITERATURE
Introduction
Jack Stand is a strong crafted metal built to ease the pressure of the car weights
and maintain the position after its elevation, This tool is being use when fixing the
problem/issue under our car, it helps us not only to fixed the position of our car after lifting
from the ground using Jack but also to minimize the danger of our mechanic.
According to James Hoffmann (2015) more than 15,000 work-related injuries were
reported by mechanics alone. Add to this a possibly large number of unreported injuries,
and the total figure could be more alarming.
Correspondingly, the innovator mechanics continuously seeks various ways to
improve the safety while working by innovating our tools and equipment, train and
seminar for safety and proper way to use tools.
This concern has been introduced to us that we the technological researcher are
reducing that risk of being in danger while the mechanics are working in this particular
aspect of repairing of Under Chassis Repair using Jack Stand
Throughout decades of repairing under car issue we use a brick, pile of wood or
even a rock with undefinable shape to support the position of our car after elevating it by
VALENZUELA CITY POLYTECHNIC COLLEGE
Kamagong St. Fortune Village VI, Parada Valenzuela City
a Jack and there is an innovation to that, and were going to provide more convenient and
with safety measure version of that product.
Background of the study
The Researchers have tried to improve jack stand tools since there have been
concerns reported in the past, such as automobile wrecks caused by weak steel that did
not last as long including those shown in the product. Because of lock is still threaded
and not fixed, if lock is missing, and there is a chance to fall out at any moment if the
Screw that you used is low quality. Another difficulty is if you make a mistake with the jack
stand location, you may end up damaging your vehicle. So we decided to conduct the
study to improve the jack stand and the product we've chosen, we'll replace the jack
stand's mechanism so it doesn't get lost, and we'll lengthen the car's handle so he has a
good grasp and can correctly balance the vehicle. We'll also make it simpler for you to
use our service.
In Valenzuela City, our improvised product will facilitate and secure the safety of
every vehicle worker, the effect of our improvised product will benefit the constituents or
workers of the government of Valenzuela
In Valenzuela City Polytechnic College, the effect of our improved product will help
us, or the automotive constructors and the next generation, in making things easier for
them to use it, and they will have no difficulty using it, and we have also improved safety.

Foreign Literature
A jack stand is an essential tool for providing a safe work environment inside and
underneath cars, trucks, or trailers.
Not only do jack stands protect technicians who need to work underneath vehicles,
but they also provide stability for personnel while loading and unloading cargo trailers.
See SafeRack’s line of jack stands
Jack stands generally consist of an adjustable A-shaped base frame, a ratcheting
post with a platform for supporting vehicles, and a ratchet handle mechanism.
VALENZUELA CITY POLYTECHNIC COLLEGE
Kamagong St. Fortune Village VI, Parada Valenzuela City
While you can use most jack stand models to lift a vehicle upward, the stand’s
ratcheting mechanism must be disengaged in order to lower it. This is virtually impossible
to do, as you would need to be able to lift the vehicle with your bare hands.
This solid mechanical stop provides exponentially more support than the hydraulics of
your floor jack.
Foreign Study
While hydraulic floor jacks can lift vehicles quickly and easily, they can (and likely
will) occasionally fall — especially cheap models. This puts you and your vehicle at risk.
Floor jacks also provide only one point of contact, which can leave your vehicle unstable
and prone to tipping if you lift it from the middle.
Not only do jack stands protect you and your vehicle from falling floor jacks, but
they also provide multiple points of contact that help you avoid tipping issues.

METHODOLOGY
Research Design
The descriptive method of research was used in conducting this study since it aims
to describe the situation of using Jack Stand as a helping hand while working in a
particular aspect of repairing car where Jack elevate the car in certain point that our
mechanic will have space under the chassis and by using this research product the Jack
stand that can stabilize the car and the safety of the mechanics from the elevation of the
car from the ground. The research Jack stand is not only for what it is called but also has
an additional feature while using: easy to use, more durable, and secure the lock of its
system.
Garcia (2014) cited that descriptive research aims to describe systematically,
functionally, accurately and objective a situation, problem or phenomena.
Calmorin and Calmorin (2015) cited that descriptive research focuses at the
present condition, the purpose of which is to find new truth. Descriptive research is also
valuable in providing facts on which scientific judgments may be based.

working along McArthur Highway Dalandanan Valenzuela City. Fifty (50) respondents of
automotive mechanics. The researchers will use Likert Scale to determine the extent
usage, safety, and durability of Adjustable Jack Stand.
Likert Scale- is a psychometric scale commonly involved in research that
employs questionnaires. It is the most widely used approach to scaling responses in
survey research, such that the term (or more accurately the Likert- type scale) is often
VALENZUELA CITY POLYTECHNIC COLLEGE
Kamagong St. Fortune Village VI, Parada Valenzuela City
used interchangeably with rating scale, although there are other types of rating scales.
Respondents may be offered a choice of five (or seven) point scale which is used to allow
the individual to express how much they agree or disagree with a particular statement. In
determining the extent usage, safety and durability of using the Adjustable Jack Stand.
