62.5 mm Key 55° The cast iron block with cross-sectional dimensions of 62.5 mm by 62.5 mm consists of two pieces. The pieces are prevented from sliding along the 55° inclined joint by the steel key, which is 62.5 mm long. The working stresses are 275 MPa for cast iron in bearing and 345 MPa for the key in shear.

1. The cast iron block with cross-sectional dimensions of 62.5 mm by 62.5 mm consists of two pieces. The pieces are prevented from sliding along the 55 degrees inclined joint by the steel key, which is 62.5 mm long. The working stresses are 275 MPa for cast iron in bearing and 345 MPa for the Key in shear.
If the block is loaded with P = 282 kN, calculate the required dimension "b" of the key.
Write your final answer in 2 decimal places with the unit of mm.
