Turbine disks are often thick near their hub and taper down to a smaller thickness at the periphery.


Turbine disks are repeatedly bulky neighboring their hub and taper down to a smaller bulkyness at the periphery. The equation'governing a variable-lumpishness 1 = t(r) disk is

(b) Develop the terminable bisect design associated delay the flimsy fashion extraneous in bisect (a).
