2. 8-10. A wood pipe having an inner diameter of 0.9 m is bound together using steel hoops each having a cross- sectional area of 125 mm². If the allowable stress for the hoops is allow 84 MPa, determine their maximum spacings along the section of pipe so that the pipe can resist an internal gauge pressure of 28 kPa. Assume each hoop supports the pressure loading acting along the lengths of the pipe. 28 kPa C Prob. 8-10 28 kPa
