One limitation of sand casting is bad surface finish. Yes or No? Why? 7. What is permeability in casting process? 8. What are the major defects in casting process? 9. Which type of casting process should be use for high melting point casting, such as cast iron and why? 10. Casting problem A certain mold has a sprue whose length is 20 cm and the cross-sectional area at the base of the sprue is 2.5 cm?. The sprue feeds a horizontal runner leading into a mold cavity whose volume is 1560 cm³. Determine: (a) velocity of the molten metal at the base of the sprue, (b) volume rate of flow, and (c) time to fill the mold (in second). mfg m1 Spring 2020 999.pptx

Quèstion 25 Which of the following describes the effect of shot peening on fatigue life? O A. It has no effect on fatigue life O B. It decreases fatigue life because of increased surface hardness O C. It increases fatigue life because of induced compressive stresses D. It decreases fatigue life because of excessive surface deformation A Moving to another question will save this response. 34°C äolo claw ENG 4)
