Two logs were used as supports for a rustic footbridge in a park. Each log spans 10 m long and is supported at both ends. Each of them is supposed to be able to carry a total of 6KN/m uniform load ( including self-weight). If the allowable stresses are 8.3 MPa in bending and 0.69 MPa in shearing, find the required minimum diameter for the log if only the bending and shearing criteria are chedked.
