(Solve for a value with the combination of mm and N)

Shown below is an idealization of a structure in which member fiD is a metal bar of width b - 25-
mm. Member BD is pin connected at both ends as shown The Yield strength of the material for BD
is SIGMA-yield - 250 MPa and the ultimate shear strength of the material for the pin at C, TAU-
ultimate 240 MPa. The factor of safety against yielding failure of member BD is FS-3.0. The
factor of safety against ultimate shear failure at the pin at C is FS-3.3. We will be able to design the
bar BD (determine thickness t) and the pin at C (determine the diameter of the pin) by answering the
questions asked
