Two links BF are made of steel with a 450-MPa ultimate normal stress and has a 6x12–mm uniform rectangular cross section. Links BF are connected to members ABD and CDEF by 8-mm diameter pins; ABD and CDEF are connected together by a 10-mm diameter pin; CDEF is connected to the support by a 10-mm diameter pin; all of the pins are made of steel with a 170 MPa ultimate shearing stress. Knowing that a factor of safety of 3 is desired, determine the largest load P that may be applied
