Forces and loads

Forces and loads

1. All physical bodies need a structure to support different forces that act on them

2. The force is anything that can deform a body or make it move or stop

3. A load is a force that acts on a structure

   • Permanent/Fixed loads are constant - don't vary over time
   • Variable loads vary over time
   • Loads produce stress on the structure of a body. Can cause different effects depending on the shape, the point of application, the direction and he shape.
