QUESTION 1
A system consists of two rotating disks with 11-400 lbm-in² and 12 = 100 lbm-in2, Initially, Disk 1 is rotating at 2000 rpm and Disk 2 is rotating at
500 rpm A clutch between the two disks is engaged such that the two disks are eventually rotating as a single unit. What is the final rotation
speed of the system in rpm?
OA 1.7×103
OB. 1.9x103
OC 22×103
OD.2.8*103
OE. None of the above
