### A concrete bridge will carry a live load that is ___% of its total load.

Explanation
A concrete bridge will carry a live load that is 25% of its total load. This means that 25% of the weight that the bridge is designed to support will be from live loads, which are temporary or moving loads such as vehicles or pedestrians. The remaining 75% of the total load will be from dead loads, which are permanent loads such as the weight of the bridge itself and any fixed structures on it. Therefore, the live load is a significant factor to consider in the design and construction of a concrete bridge.

### _________________ occurs when the ends of an object are being pushed toward each other.

Explanation
Compression occurs when the ends of an object are being pushed toward each other. This process involves applying a force that reduces the volume or length of the object, causing it to become denser or shorter. Compression is commonly observed in various situations, such as when squeezing a sponge or compressing a spring. It is an essential concept in engineering and physics, particularly in the study of materials and structures.

### ________________ occurs when the ends of an object are pulled away from each other.

Explanation
Tension occurs when the ends of an object are pulled away from each other. This is a force that is generated when there is a stretching or pulling motion applied to an object. Tension can be seen in various scenarios, such as when a rope is pulled from both ends or when a rubber band is stretched. It is a crucial concept in physics and engineering, as it helps us understand the behavior of materials under stress and the forces acting on structures.

### A(n) ________________ refers to a part of a structure that projects into space supported at only one end.

Explanation
A cantilever refers to a part of a structure that projects into space and is supported at only one end. It is a structural element that is commonly used in architecture and engineering to create overhangs or balconies without the need for additional support. The cantilever design allows for a visually appealing and functional structure by distributing the load and forces efficiently.

### When one side of an object experiences tension and the other side experiences compression, the object is experiencing  ______________.

Explanation
When one side of an object experiences tension and the other side experiences compression, the object is experiencing bending. Bending occurs when an object is subjected to forces that cause it to curve or flex. In this case, the tension on one side and compression on the other side create a bending moment that causes the object to bend.

### ________________ refers to the twisting that results when one side of an object moves in a different direction that the other side.

Explanation
Torsion refers to the twisting that occurs when one side of an object moves in a different direction than the other side. This twisting motion can cause stress and strain on the object, potentially leading to deformation or failure. Torsion is commonly observed in various mechanical systems, such as shafts, springs, and bridges, where it plays a significant role in their design and analysis.

### _________________ occurs when materials expand as they get hotter and shrink as they get cooler.

Explanation
Thermal expansion refers to the phenomenon where materials expand when heated and contract when cooled. This is due to the increased kinetic energy of the particles in the material, causing them to move more vigorously and occupy more space. Conversely, when the material cools, the particles lose kinetic energy and move less, resulting in a contraction or shrinkage of the material. This property is important to consider in various applications, such as construction, engineering, and manufacturing, as it can lead to structural changes and potential damage if not accounted for.
