340 kN Problem 1 -70mm The cast iron block consists of two pieces with 70 mm square cross-section. The pieces are prevented from sliding along the 50° inclined plane by a steel key, which is 70 mm long. Determine the smallest required dimensions b and h of the key if the failure stresse for bearing in cast iron is (o.)ai = 550 MPa and the failure shear stress for steel is ta = 450 MPa for the key in shear. Use a factor of safety of 2.2 against failure in cast iron and a factor of safety of 1.5 against failure in steel. Key 50°
