Please give step by step solution other wise don't answer I will report to Bartley team. A medium carbon steel shaft transmits 25 kW at 450 r.p.m. The diameter of shaft is 40 mm. A square key is used whose one side is equal to 1/4th of the shaft diameter and whose length is equal to 1.5 times of the shaft diameter. Find the dimensions of the key and check the key for the induced shearing stress and crushing stress.
