To calculate average speed, you measure how long it takes(T) to get from point A to point B. Then you use the formula below: speed = (B - A)/T
Formula to calculate breakeven point is as follows: Break even point = Fixed cost / contribution margin Contribution margin = Sales - Variable cost
It is the point where the principal diagonals meet.

10 - 3.65 = 6.35
no, point of inflexion is the another name of point of contraflexure
hat do we call if shear force is zero at ca point
0, bending moment is at maximum
it occur where moment becomes zero in bending moment diagram.
A point of contra flexure occurs where the bending moment in a beam changes its sign (i.e. from +ve to -ve or -ve to +ve) So, obviously at the point of contraflexure the bending moment is zero. But note that the bending moment can be zero without changing its sign. So, at the point of contraflexure the bending moment has to be zero and the bending moment must change its sign as well.
Steel reinforcements are needed at the tension face,so point of contraflexures give us an idea where to bend up/down the bars. However, general practice is to extend the bars beyond the point of contraflexure because we can't predict it accurately (also to account for shear failure).
The term "point of contraflexure" is often used in structural engineering, specifically in the context of analyzing and designing beams subjected to bending loads. In simple terms, the point of contraflexure is the location along the length of a beam where the bending moment is zero. When a beam is subjected to bending loads, it experiences tensile (positive) bending moments and compressive (negative) bending moments along its length. The bending moment varies along the beam, reaching a maximum at the points where the bending is the most significant. These points are usually located near the supports of the beam. However, in some cases, particularly in continuous beams or beams with complex loading conditions, there may be a section along the beam where the bending moment changes direction from positive to negative or vice versa. This section is known as the point of contraflexure. At the point of contraflexure, the bending moment is zero, and the beam's curvature changes direction. This point is essential in the analysis and design of structures as it affects the internal forces and stresses within the beam. Identifying the point of contraflexure is crucial for engineers to ensure the beam's stability and design it appropriately to handle the bending loads effectively. The bending moment diagram is used to visualize the variation of bending moments along the length of the beam and to locate the point of contraflexure if it exists.
