The document contains two tables of numbers. The first table lists values of the standard normal probability density function φ(x) for values of x from 0 to 3.6. The second table lists values of the standard normal cumulative distribution function Φ(x) for values of x from 0 to 2.6. Both tables show the standard normal distribution, which is commonly used in statistics.

1) The document provides steps to analyze internal forces (shear force and bending moment) in beams using the method of observations based on specific characteristics.
2) Key observations include shear forces and bending moments at each cut section based on applied loads and reactions.
3) The process involves determining applied loads, dividing the beam into sections at points of interest, then constructing shear force and bending moment diagrams by applying the observations and principles of equilibrium of forces and moments.
1) The document describes key observations used to determine internal forces (shear force Q and bending moment M) in beams using the method of sections.
2) Key observations include: forces and moments acting on a section, distribution of shear force and bending moment within beam segments, and equilibrium of forces and moments at joints.
3) The method of sections involves: determining applied loads, dividing the beam into sections, then using the observations to calculate Q and M at each section. An example application to a simply supported beam is shown.
