B
The steel tie bar shown is to be designed to carry a tension force of magnitude
P = 120 kN when bolted between double brackets at A and B. The bar will
be fabricated from 20-mm-thick plate stock. For the grade of steel to be used,
the maximum allowable stresses are: o = 175 MPa, ↑ = 100 MPa, o,
350 MPa. Design the tie bar by determining the required values of (a) the
diameter d of the bolt, (b) the dimension b at each end of the bar, (c) the
dimension h of the bar.
5. Three wood boards, each 3.5 in. wide, are joined by the 3/4-in.-diameter bolt. If the working stresses for wood
