The three steel wires are used to support the load. If the wires have an allowable tensile stress of alow - 165 MPa, and wire AB has a diameter of 6 mm, BC has a diameter of 5 mm, and BD has a diameter of 7 mm, determine the greatest force P that can be applied before one of the wires fails. %3D B 30 45 D

Determine the maximum ram force P that can be applied to the clamp at D if the allowable normal stress for the material is sallow = 180 MPa.

Rods AC and BC are used to suspend the 200-kg mass. If each rod is made of a material for which the average normal stress can not exceed 150 MPa, determine the minimum required diameter of each rod to the nearest mm.

The assembly consists of three disks A, B, and C that are used to support the load of 140 kN. Determine the smallest diameter d₁ of the top disk, and the largest diameter d₂ of the opening, and the largest diameter d3 of the hole in the bottom disk. The allowable bearing stress for the material is (b) allow = 350 MPa and the allowable shear stress is Tallow=125 MPa. C B d₁ -| A 140 kN 20 mm 10 mm d3 d2
