To calculate normal stress and shear stress on beams, it's essential to understand the definitions of moment and shear. The original poster seeks help with a homework problem but has not made any attempt to solve it, which is against forum rules. Participants emphasize the importance of showing initial efforts to receive assistance. Clarifying the definitions and concepts related to normal and shear stress is crucial for solving beam problems. Engaging with the material and attempting the problem is necessary for effective learning and support.
