13 Questions

1. Composite materials are of no use for the chemical engineers.
2. Two of the things of the composite materials are to be known so that their properties can be varied. Which of the following is one of them?
3. The total of all the masses of small particles adds up to give the total body mass of the composite body. This mass lies along with gravity gives a force vector which is being passed by ________
4. What is not the condition for the equilibrium in three dimensional system of axis for the composite bodies?
5. We use sometimes the measures to know the direction of moment. It is done by right handed coordinate system. Which is right about it for the composite bodies (consider the mentioned axis to be positive)?
6. If any external force also is applied on the distributed loading on the composite body then?
7. One of the uses of the centre of mass or centroid of the composite bodies is as in the simplification of the loading system the net force acts at the ___________ of the loading body.
8. The centre of mass for the composite body is the ratio of ________ to _________
