When we think about how beams work, different types of loads can really affect how strong they are. Here’s what I’ve found out:

1. Types of Loads:

   • Point Loads: These loads focus stress on a small area. This can sometimes cause damage in that spot.
   • Distributed Loads: These loads spread stress over a bigger area. This usually helps the beam work better.

2. Bending Moments:

   • The maximum bending moment, which we call $M$, can be found using the formula $M = F \cdot d$. Here, $F$ is the force and $d$ is how far it is from the support. A higher $M$ means the beam is under more stress, and it might fail.

3. Shear Forces:

   • Shear forces can also cause problems, especially near the supports. There’s an important formula for shear forces: $V = \frac{dM}{dx}$.

By understanding these points, we can design structures that are safer and work better!
