Step 1
Tensile force
Answer
A tensile force is a pulling force that acts on an object by exerting tension from opposite ends, essentially pulling the object apart. This force is critical in structures where materials must withstand stretching. For example, when a rope is pulled from both ends, the tensile force makes it tighter and stretches the rope. Understanding tensile force is crucial in engineering to ensure materials can handle the forces without failing.
Step 2
Countersink drill
Answer
A countersink drill is a specialized drill used to create a conical hole in a material. This type of hole helps to accommodate the head of a screw, allowing it to sit flush with or below the surface of the material. Countersink drills typically have a point angle of either 60° or 90°, which facilitates the drilling process and ensures precision in screw placement, thereby enhancing both aesthetics and functionality in assemblies.
