**Design of a Bearing Plate for a Steel Beam**

A bearing plate is to be designed for a W21x62, A36 steel beam that will sit on a reinforced concrete wall (f'c = 21 MPa) with a thickness of 200 mm. The bearing plate material has a yield strength (Fy) of 345 MPa. The end reactions include a service dead load of 150 kN and a live load of 300 kN. Determine the following using Allowable Stress Design (ASD):

1. **Required Minimum Width and Thickness**  
   Calculate the minimum width (B) and thickness of the bearing plate, assuming it is positioned at the center of the concrete wall.  
   - Use length N = 150 mm.  
   - Determine B in mm, rounding up by 10 mm or 25 mm increments.

2. **Required Thickness of the Bearing Plate**  
   If B = 300 mm and N = 200 mm, calculate the thickness (t) of the bearing plate.  
   - Determine t in mm, rounding up to the nearest whole number.

The calculations will ensure that the designed bearing plate can adequately support the given loads within the specified material properties and constraints.
