Usually this indicates an error or a misunderstanding. A single beam cannot be of uniform length.
A physical body is said to be in uniform motion when it covers same distances in equal intervals of time.
It isn't. Constant velocity? Uniform velocity across a group of objects?
The stress you induce on the beam is equal to weight hanging on the beam. The answer for the where part of the question is in the question. You said it yourself; you hang the weight from the center of the beam, therefore the stress of the weight will be in the center of the beam.
It is stress or pressure at right angles to the length, as of a beam of a bridge for example
the object is on uniform motion
Bending moment is the same throughout the beam.
A beam with a uniform cross-section.
zero stress
the efffective length of a beam is the length along the beam at which the beam will fail when a load is acting upon it. This effective length is usually near the centre of the beam as that is where the stresses are the greatest. For example a fat chick jumping up and down on the beam would reduce the effective length dramatically as the loads are semi-constant but ginormous.
Deflection of beam depends upon load and length of beam. Larger the beam, larger will be it's selfweight
All items being the same (Uniform) length.
The moment of a beam is twice that for central load vs uniform load for a simple support beam; hence it needs twice the section modulus for sizing; for fixed ends the moment is 50% higher for central load vs uniform load
The length is "stem to stern" or "bow to transom", and the width is "beam to beam".
1.50 meter from the support is the max. safe length cantilever beam
To obtain uniform strength.
A beam that has the same porperties along its entire length.
Depends on the dimensions of the beam. length * width * height
