Compression
Gravity is a force acting down on it. A normal force is acting perpendicular to the ground at the base of the structure.

The internal forces acting on a mattress are primarily compressive forces, where the mattress material is being squeezed and compacted due to the weight placed on it. These forces are distributed throughout the mattress structure to support the weight of the sleeper evenly.
The weight of the ruler is not included as a force acting on the system because it is an internal force within the system. Internal forces do not affect the overall motion of the system and therefore do not need to be considered when analyzing external forces acting on the system.
Compression is the term used to describe a force that squeezes a material or object, causing it to decrease in volume and potentially change shape. This can lead to deformation or structural failure depending on the material's properties and the magnitude of the force applied.
A bending force is an external force acting on an object that causes it to bend or deform. It is typically applied to an object from the outside to induce bending or flexing.
Quarks are the subatomic particles that respond to the strong nuclear force and have internal structure. Quarks combine to form protons and neutrons, which are the building blocks of atomic nuclei.
Body weight is an internal force because it is the force exerted by the mass of an object (in this case, the body) due to gravity acting on it. It is a result of the interaction between the body and the Earth's gravitational field.
The bending force is called a moment or bending moment. It is a measure of the internal force at a point in a structure when a bending load is applied.
The main forces acting on a free-standing structure are gravity, which pulls the structure downward, and wind or other lateral forces, which can push the structure from the sides. The structure itself also exerts internal forces to resist deformation and maintain its shape. Additionally, if the structure is on a slope, there may be forces due to the slope acting on the structure.
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
Leptons, such as electrons and neutrinos, are subatomic particles that do not respond to the strong nuclear force and are considered to have no internal structure. They are fundamental particles that are not made up of smaller components like quarks in protons and neutrons.
