Unit 1 Flashcards
What is tensile
A pulling stretching force
What is compressing
A squeezing pushing together force
What is shear
A cutting force
What are some Site constraints
The size and location of the site
The configuration of the site and shape
The orientation of the building
Access
The topography
What is creep
Where constant tensile stress produce plastic deformation and elongation over time
What are the three types of creep
Primary creep
Secondary creep
Tertiary creep
How can you speed up the process of creep
Increase the temperatures
Increase in stress
What is moisture resistance
The measure to which materials resist water
What is vapour resistance
The measure of a degree to which materials resist water vapour penetration
What is embodied energy
This is a measure of how much energy was consumed in the whole manufacturing process
Ways to prevent corrosion in metal
Painting
Galvanising
Dip coating
Consider an alternative non-ferrous metal
Different types of timber degradation
Woodworm
Wet rot
Dry rot- caused by fungus
How to prevent woodworm
Apply insecticide timber treatment
Replace wood that has been exposed to woodworm
Maintain good ventilation and address any signs of damp
How to prevent wet and dry rot
Apply anti-fungal timber treatment
Paint timber to exclude moisture
Address any signs of damp
Maintain good ventilation
Remove and replace any infected timber
What is embodied energy
The amount of energy consumed in the whole manufacturing process
