The size of ceiling joists is primarily influenced by the span they need to cover and the load they must support. Other factors include the type of wood used for the joists, the spacing between joists, and any additional load considerations like heavy fixtures or storage. Local building codes and regulations also play a role in determining the size of ceiling joists.

What are the factors that affect settlements?
Factors that affect settlements include availability of natural resources, topography and climate, transportation networks, proximity to water sources, economic opportunities, and historical and cultural influences. These factors can impact the location, size, and growth of settlements.
Which is a density-independent factor in controlling population?
volcanic eruption
Why are populations in nature called dynamic?
Populations in nature are called dynamic because they are constantly changing due to various factors such as births, deaths, immigration, and emigration. These changes can lead to fluctuations in population size and composition over time. This dynamic nature is essential for the adaptation and survival of species in response to environmental changes.
What is the population size of predator species directly controlled by?
The population size of predator species is typically controlled by the availability of prey, competition with other predators, and environmental factors like habitat and climate. The population size can fluctuate based on these factors, leading to dynamic predator-prey relationships.
What factors influences both carrying capacity and population density?
Factors that influence both carrying capacity and population density include availability of resources like food and water, habitat suitability, competition for resources, predation, disease, and environmental conditions such as climate and topography. These factors can affect the ability of a habitat to support a certain population size, as well as the distribution of individuals within that habitat.
What size of beam do you need to span 18 ft?
For ceiling joists, the minimum dimension per the IBC is a 2 x 12 inch, with spacing dependent on the load. Ideally, these would be screwed to blocking between the joists.
What does it cost to remove a wall?
Removing a wall cost $250 depending on the size. Labor may cost as much as $800, and $75 for ceiling joists.
How much weight can joists hold?
That depends upon the size of the joists & grade/species of wood
What two factors affect a planets revolution?
Two factors that affect a planets revolution are distance from the sun and size.
What are the factors that affect the luminosity of the star?
Its size and temperature.
Which factors affect a populations growth regardless of the population size?
The basic needs like food, shelter are some of the factors that affect the population's growth regardless of the size.
What Factors affect consumer spending?
The factors that affect consumer spending are: Size of Income, Future Expenditures, and Social Influences.
What factors does not directly affect family size and composition?
What factors? You didn't list any.
If you know the span how to calculate the ceiling joists size?
if you are USA based then this could help you http://www.awc.org/technical/spantables/tutorial.htm in the UK which has differing requirements this can help http://www.rushcliffe.gov.uk/upload/public/attachments/39/TA008ceilings.pdf
What size of floor joist should you use?
Different situations call for different joists. Generally floor joists are 2 x 12.
What are the factors that affect the size the shape and the color of the cloud?
By the wind
Which factors affect a populations growth regardless of the populations size?
density - dependent limited factors
