please help, due at midnight! thanks

Based solely on shear considerations, for a working stress of 1.2 MPa in shear the maximum allowable intensity of w0 will be limited to 15.6 kN/m 11.3 kN/m 9.2 kN None of the above For a uniform load intensity w0 = 6 kN/m the magnitude of the maximum bending stress acting in the beam will be equal to 4.48 MPa 3.62 MPa 9970 kPa None of the above For a uniform load intensity w0 = 6 kN/m the magnitude of the maximum stress acting in the beam will be equal to 8.42 MPa 0.928 MPa 1250 kPa None of the above The wooden rectangular beam is subjected to a concentrated load P and the uniform load distribution indicated. The working stresses for the material are 10 MPa in bending and 1.2 MPa in shear. Based on the information provided the maximum allowable magnitude of the concentrated load P will be equal to
