32″ is correct. But in many jurisdictions, the door slab counts against the opening. Again, this why 36″ opening are universally taken as the accessible door width.

What is the difference between stanchions, posts, trusses, and struts?
Stanchion – Literally means an upright element. Some industries call posts or bollards that have tied loads on them stanchions. Post – Vertical load-bearing element. Larger or thicker versions tend to be called columns. Truss – A beam or similar, roughly horizontal, element composed of a number of sub-elements. Think of a beam with most …

How we could draw the bending moment diagram, of a fixed beam without any applied load, and without considering self weight as udl? A beam without any shear force, do have any bending moment?
No applied forces, including no self-weight. then the bending moment diagram and the shear diagram are a straight line. This is because no forces have been applied to the beam.
Could the Three Gorges Dam be at risk for collapse from an earthquake since it sits on a fault line?
The Three Gorges Dam is a gravity dam, so it would tend towards more earthquake-resistant than most comparable objects. A gravity dam is a type of structure that doesn’t rely on the strength of the materials to resist the forces of reservoir and earthquakes but rather is built to weigh so much that these forces …
Can grout be used as cement? Why or why not?
Technically, yes. Practically, there are far better choices. Let’s assume you are talking about tile grout. Its job is to bond to ceramics or stone and provide a strong wear surface. We really use a wide array of different materials that we call grout for this job, but as long as they do the two …

Are tall buildings safe?
If you consider your single story home on the ground safe; then yes. The problems you encounter in tall buildings are different more so than greater. you should be pleased to know that a great deal more research, engineering, and skill in building tall buildings than goes into building a single story home. And yet, …
How far does a fence have to be off property line?
Typically there are no restrictions on the location of fences at residential locations. Most cities, or other jurisdictions, are more concerned about the height and materials the fence is composed of (if it is over 6′ and how flammable it may be).
Why are some concrete posts of elevated rail systems not aligned at the center of the girder which will hold the 2 rails of the train?
Trains have very specific requirements for how much they can rise/fall or turn. As such, the available locations to place a support can easily not line up with the track. So they place the support as near as possible and provide a secondary member to support the rails. You often see this with freeway interchanges …
In flexural design for concrete, is steel reinforcement required? Why?
Strictly speaking, no. Without reinforcement, steel or otherwise, you are looking at gravity structures that mostly rely on compressive strength. Any modern application of concrete pretty much calls for reinforcement. In different terms, once your concrete object (this is a solid concrete object) gets a dimension that is around three times more than the shortest, …

Say I’m in a fair-sized city. How far down would I have to dig to no longer be in that city?
Legally, you’re still in the city at any depth this side of the center of earth. If you’re looking for undisturbed soil: Suburban – houses: 5′. Suburban – streets: 20′ in most cases, but at low as 60′ for large deep utilities. Suburban – commercial buildings: 20′ in most cases, but as low as 40′. …
