What else can I help you with?
Why might a sidewalk be built with periodic breaks in it?
As the weather changes the concrete expanse and contracts. The joints aka cracks act as a breaking point if the concretes put under to much pressure.
Are riveted joints better than welded joints?
Better in what way? Rivited joints are generally cheaper while welded joints are generally stronger.
What are the four types of wood joint?
The four common types of wood joints are butt joints, miter joints, dovetail joints, and lap joints. Butt joints connect two pieces of wood end to end or edge to edge, while miter joints are created by cutting the ends of two pieces at an angle, typically 45 degrees. Dovetail joints are interlocking joints often used in drawers for strength and aesthetics, and lap joints involve overlapping two pieces of wood, providing stability and support. Each joint type has its specific applications and advantages in woodworking.
Can you give me some examples for built environment?
The built environment encompasses various human-made structures and spaces, including residential buildings like houses and apartments, commercial spaces such as offices and retail shops, and public infrastructure like parks, bridges, and transportation systems. Examples also include schools, hospitals, and recreational facilities. Additionally, urban planning elements like streets and sidewalks contribute to the overall built environment. These structures and spaces significantly influence social interactions, accessibility, and sustainability in communities.
What is the control joints?
Control joints (often confused with expansion joints) are cut into the concrete or asphalt, and are different from expansion joints as shown in the photo. The joints are cut into the structure at regular intervals allow cracking to occur in a controlled fashion. Road control joints can be sealed with hot tar, cold sealant (such as silicone), or compression sealant (such as rubber).
What are the surface of joints lined with?
With periosteum
Why is important to place gaps at regular intervals in sidewalks?
To prevent sidewalks from cracking in random spots and breaking apart, builders make lines in sidewalks. The technical term for sidewalk lines is contraction joints. Contraction joints are placed in fresh concrete before the concrete dries and has a chance to create its own joints, which we call cracks.
Why does the expansion joints in a sidewalk get narrow in the summer and get wider in the winter?
Expansion joints in sidewalks are designed to accommodate the natural expansion and contraction of the concrete due to temperature changes. In the summer, the concrete expands with the heat, causing the joints to narrow. In winter, when the concrete contracts in the cold, the joints widen to prevent cracking and damage to the sidewalk.
Why does sidewalks have seams joints?
Smaller pieces of concrete tend to crack less.
Why do sidewalk have built in cracks every few feet?
Sidewalks have built-in cracks, often referred to as expansion joints, to allow for the natural expansion and contraction of the concrete due to temperature changes and moisture. These joints help prevent the concrete from cracking unevenly, which can lead to structural damage. Additionally, they facilitate drainage and can help manage the natural settling of the ground underneath. Overall, these cracks are essential for maintaining the longevity and safety of the sidewalk.
Are the most fibrous joints joined by joint cavity?
Synovial joints have a fibrous articular capsule lined with synovial membrane surrounding a joint cavity.
How was transportation made possible in Tenochtitlan?
Sidewalks were built, and boats passed through the canals.
Why does the roads and sidewalks have spaces?
Roads and sidewalks have spaces, often referred to as joints, for several reasons. These joints allow for expansion and contraction of materials due to temperature changes, helping to prevent cracking and structural damage. Additionally, spaces can accommodate drainage, preventing water accumulation and improving safety. They also facilitate maintenance and repairs without requiring complete reconstruction.
The joints between the vertebrae of the backbones are best described as?
The joints between the vertebrae are known as facet joints. They provide stability and allow for movement in the spine. Facet joints are lined with cartilage and surrounded by a joint capsule that contains synovial fluid.
What joints have a fibrous capsule lined with synovial membrane surrounding a joint cavity?
Synovial joints, such as the knee or shoulder, have a fibrous capsule lined with synovial membrane. This membrane secretes synovial fluid which lubricates the joint and nourishes the cartilage surfaces. The joint capsule helps provide stability and support to the joint.
What is Types of junctions?
1. Bony Fusion- bones fused together; no movement (also called synostoses joints)2. Fibrous Joints-immovable joints (synarthroses) that have fibrous connective tissue between the articulating bones; little to no movement3. Cartilaginous Joints- cartilage between the bones4. Synovial Joints- have a joint cavity lined by a synovial membrane
Who was the king of sidewalks?
The King Of Sidewalks
