Question
! Required information A 24-mm-diameter uniform steel shaft is 600 mm long between bearings. Take the value of acceleration due to gravity g to be 9.81 m/s2, the value of y for carbon steel to be 76.5 × 103 N-m-3, and the value of Eto be 207 x 10⁹ N/m². NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the critical speed of the shaft in rads/s? (You must provide an answer before moving to the next part.) The critical speed of the shaft is 847.5 rad/s.
