Determine the hoop stresses at the inside and outside surfaces of a long thick cylinder which is rotated at 4000 rev/min. The cylinder has an internal radius of 80 mm and an
external radius of 250 mm and is constructed from steel, the relevant properties of which
are given above. How would these values be modified if under service conditions the
temperatures of the inside and outside surfaces reached maximum levels of 40°C and 90°C
respectively? A linear thermal gradient may be assumed. For steel a = 11 x 10-6 per c.​

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
