Question

2. All of the following statements are true regarding wood versus metal except: a) Wood has better electrical insulation which decreases with moisture content b) Wood structures dampen vibrations much better than metal, due to internal friction within the materials c) Under sustained loads wood stops to deform d) Wood has much better R value than metals

Answer 1

All of the following statements are true regarding wood versus metal except:

c) Under sustained loads wood stops to deform

Step-by-step explanation:

Wood is known to deform under stress. It undergoes warping, thereby, losing its original straight shape when its moisture unevenly dries up. Even concrete deforms under long-time loads. Similarly, wood, under sustained loads, experiences faster deformation than it ordinarily warps. To prevent further wood deformation, it must be treated, and its moisture dried up evenly.
