A shaft is to be designed to transmit 10kW of power at 2000rpm. The shear stress must be kept below 300MPa and the shear modulus is 75GPa. The shaft is 1m long and must have less than 2표of rotation from end to end. Determine the minimum required diameter.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
