2. The heaviest and lightest strings on a certain violin
have linear densities of 3.0 and 0.29 g/m. What is the ratio
of the diameter of the heaviest string to that of the
lightest string, assuming that the strings are of the same
material?

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
why making capacity is more than breaking capacity?
