Formula to calculate breakeven point is as follows: Break even point = Fixed cost / contribution margin Contribution margin = Sales - Variable cost
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
It is the point where the principal diagonals meet.
mean
force x perpendicular distance from a specific, defined point
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.
The point of contraflexure is a critical location in the bending moment diagram of a structural member, such as a beam or a column. It is the point along the member's length where the bending moment changes direction from positive (sagging) to negative (hogging) or vice versa. In simple terms, it is where the bending moment is zero. The significance of the point of contraflexure lies in its effects on the behavior and design of the structural member. Here are some key points highlighting its importance: **Zero Bending Moment:** At the point of contraflexure, the bending moment is zero, meaning that there is no bending action or flexural stress acting on the member at that specific location. This point divides the member into two segments, one subjected to sagging and the other to hogging bending moments. **Critical Design Location:** Engineers and designers pay special attention to the point of contraflexure when analyzing and designing structural members. This is because it often represents a critical location where the member is subjected to the highest bending stresses. **Cracking and Deflection:** The point of contraflexure is associated with increased cracking potential in reinforced concrete members, particularly beams. The tensile forces on the bottom fiber and compressive forces on the top fiber cause potential cracking at this location. **Reinforcement Design:** The location of the point of contraflexure influences the design of reinforcement in reinforced concrete beams. Engineers often place additional reinforcement near this point to enhance the member's capacity to resist bending stresses. **Load Distribution:** Understanding the point of contraflexure helps in determining the distribution of loads and reactions along the length of the structural member. **Safety and Serviceability:** By analyzing the bending moment diagram and identifying the point of contraflexure, engineers ensure that the structural member meets safety and serviceability requirements, such as deflection limits. **Critical Analysis:** During the analysis of complex structures subjected to multiple loads and supports, the point of contraflexure can provide valuable insights into the behavior of the member and aid in determining the critical locations for design consideration. In conclusion, the point of contraflexure is a significant location in the bending moment diagram of a structural member. Its importance lies in identifying the locations where bending moments change direction and understanding the stresses and deflections associated with these points. Engineers use this information to design safe and efficient structural members that can withstand the applied loads and support the intended loads without failure.
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.
