A wooden log is to be used as a footbridge to span 3.50-m gap. The log isrequired to support a concentrated load of 30 kN at midspan and a uniformlydistributed load of 20 kN/m throughout the span. If the allowable stress inshear is 0.7 MPa.1. What is the diameter of the log that would be needed? Assume the logis very nearly circular and the bending stresses are adequately met.Neglect the weight of the log.2. If the log is to be trimmed to have a square cross section, whatshall be the resulting dimensions (Round off to the nearest wholenumber).3. Compute for the maximum flexural stress of the beam loading.
