It looks like you’re asking how to determine the normal reaction on each of the two wing wheels at point **B**. However, the image **does not provide the necessary diagram, forces, or numerical data** required for a specific calculation. But I can **explain the general steps** you would take to solve such a problem: --- ## Step 1: Draw a Free-Body Diagram (FBD) **Explanation:** Draw the aircraft (or object) with all forces acting on it, including: - Weight (W) acting at the center of gravity. - Normal reactions at all wheel locations (main wheels, wing wheels at B, etc.). - Any other external forces if given. *Purpose:* This helps visualize all forces and their locations, which is necessary for equilibrium equations. --- ## Step 2: Apply Equilibrium Equations **Explanation:** Use the conditions for static equilibrium: - Sum of vertical forces = (to find total upward normal forces) - Sum of moments about a convenient point = (to solve for individual reactions) For example, if the total normal force is shared equally by the two wheels at B: \[ N_B = \frac{\text{Total reaction at } B}{2} \] *Purpose:* Solving these equations will give you the normal reaction at each wheel. --- ## Final Answer (General Form): \[ N_B = \frac{\text{Total normal reaction at B}}{2} \quad \text{[with appropriate units]} \] --- **Note:** If you provide the actual diagram or the values (weight, distances, etc.), I can give you a detailed numerical solution!
