4. Question
For the truss shown in the figure, the zero force members are
- AC and DC
- CE and BC
- AD and DE
- AD and BC
Correct

Consider joint D, for the truss shown in the figure. We assume force F₁ in member DC, F₂ in member DA and F₃ in member DF. This joint is unloaded and the forces F₂ and F₃ are collinear. So, F₁ must be zero. Similarly, forces in the members EF and HG are zero.

Question 14 of 25

14. Question
Chills are used in moulds to
- achieve directional solidification
- reduce the possibility of blow holes
- reduce freezing time
- Smoothen metal flow for reducing splatter
Correct

A chill is an object used to promote solidification in a specific portion of a metal casting mould. Normally the metal in the mould cools at a certain rate relative to thickness of casting. When the geometry of the moulding cavity prevents directional solidification from occurring naturally, a chill can be placed to help promote it.

Question 15 of 25

15. Question
Carburised machine components have higher endurance limit, because carburization
- raises the yield point of the material
- produces a better surface finish
- introduces a compressive layer on the surface
- suppresses any stress concentration produces in the component.
Correct

Carburizing or Carburization is a heat treatment process by which carbon is introduced into a metal.
Carburization can be used to increase the surface hardness of low carbon steal. Because of carburization a compressive layer is produced on the surface which increase the hardness of the metal.
