Answer

Brief Explanations:

For the first question, a 2x6 on - edge is difficult to grab as a handrail. For the second question, freeze - thaw cycles can cause spalling and mortar damage near the bottom of an exterior masonry column as water seeps in, freezes, expands, and causes damage over time.

Answer:

  1. it can be difficult to grab
  2. freeze/thaw cycles
