Answer the following statement(s) true (T) or false (F)
1. The modulus of rigidity is a measure of how easily a material will stretch when pulled or how well the material will shorten when pushed. 2. Concrete is stronger in tension than it is in compression. 3. The coefficient of linear expansion can be used to determine the change in the length (per original length) of a material that would occur if the temperature of the material were changed. 4. The value of heat capacity represents the amount of thermal energy required to raise the temperature of 1 kilogram mass of a material by 1°C. Materials with large heat capacity values are good at storing thermal energy. 5. The lower the viscosity value is, the more resistance the fluid offers to flow.
