Distributing loading Flashcards
What is the load per volume?
This could be the distributed weight of a material. For example, steel has a density of 7700kg/m^3. assuming gravity constant g = 10m/s^2, this is a unit weight y = 78kN/m^3 (load per volume)
What is the load per area?
This could be fluid pressure (liquid e.g., water, gas e.g., air). Let’s consider a swimming pool with a horizontal floor that is filled with water. The same pressure intensity acts across the whole floor, creating a load per area (Unit: N/m^2 or kN/m^2)
How do we convert distributed loads into statically equivalent resultant loads?
To work with distributed loads in equilibrium equations, we convert them into statically equivalent resultants. This means the resultant load must have:
- Direction
- Magnitude
- Line of action
How do we convert distributed loads into the resultant direction?
The resultant direction will be the same as the distributed load
How do you work out the floor horizontal?
What is load per unit length?
What is a linearly distributed load (LDL)?
How do we convert the magnitude into resultant direction?
How do we convert the line of action into resultant direction?
How do we work out common UDL cases?
How do you work out the common LDL cases?
What is the general terminology for types of loads?
What is a bar?
In a truss, how are external loads applied?
