Which component is typically used to provide spacing or support in mechanical constructions?

• A. Screws
• B. Washers or Spacers
• C. Bearings
• D. Nuts

Answer: (B)

Washers or spacers are designed specifically to provide spacing or support in mechanical constructions. These components serve a vital purpose by preventing direct contact between parts, distributing loads, reducing friction, or adding clearance. Using washers can protect surfaces from damage by creating a buffer between materials, while spacers are often used to maintain a specific distance between components. This is particularly important in assemblies where precise spacing is vital for operation, such as in the alignment of rotating parts or in situations where thermal expansion occurs. Other components like screws, bearings, and nuts play different roles. Screws primarily serve to hold components together; bearings enable rotational or linear movement between parts by reducing friction; and nuts are typically used in conjunction with bolts or screws to secure components. Thus, while these elements are essential in mechanical design, they do not primarily focus on providing spacing or support like washers and spacers do.
