A load P is supported as shown by asteel pin that has been inserted in a short wooden member hangingfrom the ceiling. The ultimate strength of the wood used is 60 MPain tension and 7.5 MPa in shear, while the ultimate strength of thesteel is 145 MPa in shear. The diameter of the pinis d = 14 mm and the magnitude of the loadis P = 20 kN. Determine the required valuesof b and c if the factor ofsafety for the wooden members is the same as that found inpart a for the pin
