Properties Of Materials

Question 1

strength

Answer 1

The ability of a material to resist force. All materials have some degres of strength-the greater the forse the material can resist, the stronger the materials. Some materials can be strong in tension but weak in compression , for example mild steel. The converse can also be true, as is the case with concrete, which is strong in compression but weak in tension. Hence, the reasan that concrete is often reinforeed with mild
steel

Question 2

Elasticity

Answer 2

The ability of a material to return to its original shape or length once an applied load or force has been removed. A material such as rubber is described as elastic because it can be stretched but when it is released it will return to its original condition
