When the inner cylinder is rotating and the outer cylinder is stationery, in reality, viscous torque is produced both from the annular gap around the inner cylinder (M3) as well as from the flat bottom of the inner cylinder as it rotates above the flat bottom of the outer cylinder (M4). i. Obtain an expression for M3 and M4. ii. If the values of M4 needs to be 1% of M3 (or less than 1%) - obtain a plot of (b/a) as a function of (R; / h). If the values of M, needs to be 1% of M3 (or less than 1%), obtain the value of b when a = 0.20 [mm], R; = 50 [mm], h = 80 [mm], M3 =0.0245 [N] and 2 = 1.2 [s']. iii. %3D
