materials
3x pine | softwood used heavily in the building industry | used because it is very strong yet soft enough to work with for carpentry
| 1200x35x35mm
1x ply | manufactured wood panel made from thin sheets of wood (vaneers) | glued together with grains at right angles from the adjacent layer to produce a strong panelling material

ply
w o r k s h o p our design
the task was to design a beam that spanned a we used
pine
40mm 1 meter gap
2 pieces of pine timber that we cut down to 1100mm
1100mm
100mm
we used smaller cut pieces of timber to connect the two longer pieces together using screws we then nailed the piece of ply to the top of the wood to add lateral support and added strength

w o r k s h o p structual performance
our design as the presseure was placed onto the middle our member the pine began to buckle
| as more presseure was added the beam was being |
our design
compressed on the top and pulled with tension on the bottom
this eventually split the pine timber at the bottom due to the large amount of tension occuring
| the piece also broke in this specific
place due to the screws that were used weaking the piece of timber group

as the pressure was first added the pine began to bend quite
| as more pressure was added the ply began to buckle out resisting the compression of the mallet | this showed how flexible the ply was | eventually the pine sheard at the bottom dramtically
however the ply did not split group

as the pressure was first initiated the pine started to buck much like the other designs
| as more pressure was added the piece was able
to bend more due to the use of ply wood on the bottom and top
| in the end both the pine and the ply were sheared at the bottom showing the limitations of ply panelling

w o r k s h o p definitions cross section
span
span
compression
| span is the horizontal distance between the two vertical
supports that hold up a beam cross section
| a cross section is a 2d drawing of a structure
that has been cut through strength
| strength is the capacity of any given material to
withstand any form of stress or strain compression
| compression is a type of stress in a structure that
leads to downward forces and load paths tension
tension
felxion
shear
| tension occurs when a stucture is pulled where the load
paths move outwards from the centre of the structure flexion shear
| flexion is the act of a structure bending or being bent
| shear is the srain or stress on a sctructure resulting in the
lateral movement of the material
| deflection is the degree or amount a structual element is displaced under a load, measured in distance or angle
deflection
| buckling is when a structual element is bended, warped or crumpled under pressure and/or heat buckling
deflection
buckling
