1. The rocker or roller support is commonly used for supporting one end for trusses to allows freedom for expansion or contraction of the members due to a change in temperature or application of loads. 2. Many of the polymer based composites are subject to attack by chemicals or solvents, just as the polymers themselves are susceptible to attack and absorb moisture. 3. If the biological material is produced from toxic substances, it is not compatible with the tissues of the body and may lead to side reactions.
