The types of loads and their conditions play a big role in how structures handle bending and shear stress. This is really important for making sure buildings and bridges are safe and work properly.
Point Loads: These focus stress on specific spots. Imagine putting a heavy weight on one spot; that’s a point load.
Distributed Loads: These spread stress evenly across a length. Think about how a long, heavy beam pushes down on the supports along its entire length.
Bending Stress: This is how much stress is caused when something bends. It can be figured out with a simple formula where you divide the moment (the force causing the bend) by the section modulus (the strength of the shape).
Shear Stress: This happens when forces slide against each other. You can calculate it by dividing the shear force (the force trying to slide something) by the cross-sectional area (the size of the beam or support).
All these things together affect the overall stress situation in a structure. It's important to study them carefully to avoid any accidents or failures.
