- Granule strength is very important in pressing powders. The force applied to a granule with a radius of 1 mm is 0.5 Newton. Calculate the breaking strength of the granule. b) It is observed that the pressed granules break easily during pressing. Write down the reasons of this situation and what would you take precations to solve this problem? Why? (please write down 3 precautions with reasons). odluckarrow_forwardIn powder processing, a cylinder with a diameter of 2 inches and a height of 10 inches is to be made from fine copper powders. A single-action press is used for compaction. If the average density of the green product is 7 g/cm3 at the bottom half of the cylinder, estimate the compaction pressure at the punch surface. Assume no friction between the powders. The coefficient of friction between particles and containers is 0.2.arrow_forwardلانقطة واحدة of Warm working The advantages over cold working are: 1) forces and power are higher,2) more intricate work geometries possible, and 3) need for annealing may be reduced .or eliminated T F Blow molding is an important industrial process for making one- piece hollow plastic parts with thick .walls T Sly The sequence of the Blow Molding is automated and often integrated with downstream operations such .as bottle filling and labeling T لنقطة واحدةarrow_forward

- A thin steel disk of an oil separator of 100mm outside diameter is shrunk onto a solid steel shaft of 20mm diameter. The system is to be designed to make sure the disc does not become loose at speeds lower than 100000rev/min. Determine the shrinkage allowance required in order to avoid separation disc and shaft, at a speed of 100000rev/min. For the material assume a Young's Modulus, Poisson Ratio and density of 210GPa, 0.3 and 7850kg/m³ respectively.arrow_forward2arrow_forwardMoulds for blow moulding can be made using aluminium whereas moulds for injection moulding are usuallymade out of tool steel, why?arrow_forward
