If the initial temperature of the billet is high, the extrusion pressure will be __________ as compared to billet having a lower temperature.

If the initial temperature of the billet is high, the extrusion pressure will be __________ as compared to billet having a lower temperature. Correct Answer lower

If the initial billet temperature is high, the required stress to cause the plastic deformation will be lower. This is because of lower stress for dislocation movement. That is why billet is heated before practicing extrusion.

Seven people A, B, C, D, E, F and G live on separate floors of a 7-floor building. Ground floor is numbered 1, first floor is numbered. 2 and so on until the topmost floor is numbered 7. Each one of these having a different cars-Cadillac, Ambassador, Fiat, Maruti, Mercedes, Bedford and Fargo but not necessarily in the same order. Only three people live above the floor on which A lives. Only one person lives between A and the one having a car Cadillac. F lives immediately below the one having a car Bedford. The one having a car Bedford lives on an even-numbered floor. Only three people live between the ones having a car Cadillac and Maruti. E lives immediately above C. E is not having a car Maruti. Only two people live between B and the one having a car Fargo. The one having a car Fargo lives below the floor on which B lives. The one having a car Fiat does not live immediately above D or immediately below B. D does not live immediately above or immediately below A. G does not have a car Ambassador. Question : How many people live between the floors on which D and the one having a car Bedford ?
