WOODWORK: AT3
I plan on conducting an experiment to compare the strength
and exibility of timber against that of particleboard for my AT2
product. The experiment will be very important in giving primary
data that will lead to a very informed decision on which material
is to be used in making a step ladder that is safe and durable. It
will be important to understand what weight each material can
bear without excessive exing to make the ladder reliable.
Particleboard nds its usage in making furniture, cabinets,
shelves, and ooring due to its inexpensiveness and smooth
uniform surface. It is an engineered wood product, made from
wood chips, sawmill shavings, or sawdust combined with a
synthetic resin or another binder, pressed and extruded. While
fairly easy to work, particleboard is less resistant to moisture
compared to other wood products.
Solid timber, especially Meranti, is commonly used in furniture,
interior trim, cabinetry, and building construction due to its
attractive appearance and strengths. Normally, Meranti is a
softwood with straight grain and even texture. It is malleable,
lightweight, easily workable, and can be stained or painted into
a variety of nishes. Therein lies the ease with which this wood
can be used in a variety of functions: from decorative Maranti and Solid timber
applications to structural ones.
- Materials and Equipment:
-
- Solid Timber Samples:
- Depth: 14mm
- Width: 20mm
- Length: 200cm
- Solid wood; strong and durable.
- Particleboard Samples:
- Depth: 20mm
- Width: 40mm
- Length: 200cm
- Engineered wood chips and resin, glued together; usually used in making furniture.
- Meranti Samples:
- Depth: 10cm
- Width: 10cm
- Length: 200cm
- Softwood; straight grain; light in weight; strong enough for decorative and structural uses.
- Two Supporting Platforms: for the test samples to rest on.
- Weights (blocks of 10kg to 30kg): for applying loads to the
samples for testing muscular strength and exibility.
- Measuring Device: such as a rule or calliper for measuring
de ection and any changes in the dimensions.
- Load Application Device: such as a hanging arrangement for
weights, to be applied roughly uniformly over the body during the
test.

, - Safety Device: to be worn by the worker, like gloves and goggles.
- Record Sheet: to write measurements and notes.
PROCEDURE:
1. Preparation:
◦ Ensure all materials and equipment are available and in good condition.
◦ Measure and record the dimensions (depth, width, length) of each material sample
to ensure accuracy.
2. Setup:
◦ Place the support platforms at a xed distance (1.5 meters apart) to hold the
sample.
◦ Secure the rst sample (Timber 1) horizontally between the two platforms, ensuring it is level
and stable.
3. Load Application and Measurement:
◦ Begin with an initial weight of 10kg. Carefully hang the weight at the center of the sample.
◦ Measure and record the de ection ( ex) at the midpoint of the sample using the measuring
device.
◦ Incrementally increase the weight by 10kg, measuring and recording the de ection at each
stage (20kg and 30kg).
4. Repeat for Each Material:
◦ Repeat the load application and measurement steps for Particleboard and Timber 2
samples.
◦ For each weight increment, ensure accurate de ection measurements and record the data.
