That question cannot be answered without knowing the load on the beam.
how many tons nutmeg ABCD load in 20 feet container
Assuming the load is evenly distributed from the wheel to the handle, it would be 2 feet. But if it is a wheelbarrow, there is more load over the wheel than load at the handle end when lifted, so my estimate would be 1.5 feet from the wheel.
The web should be in vertical.
Many.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
That question cannot be answered without knowing the load on the beam.
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
It all depends on the dimensions of the steel beam
The shear center is the point on a beam cross section at which an applied shear force (lateral load or load parallel to the cross section) will produce bending but no twisting of the section. The center of twist is a point in a cross section that remains stationary when a twisting moment (torque) is applied on that cross section. The shear center and twist center are the same point only when the beam is rigidly supported.
That depends on many other factors. What is the beam material? Is the load a point load concentrated in one spot, or is it uniform across the total span? Specing beams is something that should be left up to a qualified person.
when the load is applied in the beam then deflection takes place. the nature of the deflection depends on the support provided on it
38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.

With a span of only 8" you can probably use a wood beam, but without a set of plans no one can accurately answer your question.
the beam gets bend if the load is more then the resisting force of the beam and if the resisting force is more then the load it doesn't bends.
The strength, S, of the beam is Mc/I where M = max moment to fail = PL/4 for load concentrated in the middle of the beam or WL/8 for uniformly distributed load. Here P is the concentrated load, W = distributed load, c = distance to outer fiber from neutral axis and I the area moment of inertia of the beam. L = length Solving for load maximum, P = 4IS/Lc for concentrated center load W = 8IS/Lc for distributed load
