PHYSICS OF MATERIALS
Assignment :1
Q.no 1:
• The material used for making spoon or fork should have all the
mechanical properties to make it rigid and unbreakable,while serving
food.
• The material should not react with food or air.
• It should not have thermal expansion or thermal conductivity.
• It should be electrically dormant,especially for children.
• It should not get magnetized in earth’s magnetic field
For example:
• Plastic spoons or forks are not conductors of heat and hence hot food can
be easily served by holding it in our hand,but it is chemically reactive.
• Silver spoons have good mechanical properties but it is a good conductor
of heat and electricity.
Q.no 2:
Given: consider a 2-D problem
