A rectangular solid beam length of 3m is simply supported at its ends it has width of 100 mm and depth of 200 mm the beam is subjected to a uniformly disturbed load of 2 tonnes/m and a point load of 200N at its centre positionI) determine the maximum stress due to bending (occurring at the centre point)ii) determine the value of the radius of the curvature of the neutral layeriii) the factor of safety if the maximum allowable stress of the material is 100MPa
