Assumptions
The beam is symmetrical about Y-Y
The traverse plane sections remain plane and normal to the longitudinal fibres after bending (Beroulli's assumption)
The fixed relationship between stress and strain (Young's Modulus)for the beam material is the same for tension and compression ( σ= E.e )
The basic assumption of the kinetic theory of matter is that all matter is made up of particles (atoms or molecules) that are in constant motion. This motion increases with temperature and decreases with lowered temperature.

A hypothesis is a proposition made as a basis for reasoning, without any assumption of its truth. It is an unproved theory or conjecture that may be the basis for experimentation.
An assumption based on prior experience is when we anticipate a similar outcome or situation based on past encounters or knowledge. This assumption is made without having concrete evidence or information to support it but relies on our past understanding of similar events.
Alfred marshall made a heroic assumption of 'cetris paribus' which means other things being equal/constant in economics. This assumption he used for the theories he put forth viz. theory of demand,theory of supply,theory of diminishing marginal utility,etc. Most of his theories come under the sub field- micro economics. The assumption of cetris paribus is the main, there are many others for each law besides cetris paribus.
A philosophical assumption is coming to a conclusion based on having a background and knowledge of a particular subject or discipline.When a philosophical assumption is made, a person uses their background knowledge of a subject to answer questions or make a decision using the values and principles of that subject.
Cost Flow Assumption
Kinetic molecular theory assumes that gases consist of particles (atoms or molecules) in constant random motion. It also assumes that gas particles are small compared to the distance between them. Additionally, the theory assumes that gas particles are in continuous, rapid, and random motion.
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.
The additional assumption made regarding the value of centripetal acceleration is that it remains constant throughout the motion of the object. This assumption simplifies calculations and analysis when dealing with circular motion problems.
When he found the "Dear John" letter and the closet empty, he made the assumption his girl friend had left him.
Unlike an optical lens, maximum 'bending' occurs closest to, and minimum 'bending' furthest from, the center of a gravitational lens.
