hat do we call if shear force is zero at ca point
Alternates are fill-in-the-blank version of this Q. are the same distance from a point and a line
The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.
The set of all points a given distance from a center point is a circle. The given distance is the radius, and the given point is the center. Or, in 3 dimensional space, a sphere.
hi
A vector.
no, point of inflexion is the another name of point of contraflexure
it occur where moment becomes zero in bending moment diagram.
Ah, the point of contraflexure is a special place where the shear force is zero. It's like a little moment of balance and harmony in our structural world. Just imagine a gentle stream flowing peacefully through the woods - that's the feeling we get when we reach the point of contraflexure.
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 point of contraflexure in a beam is where the bending moment changes sign, indicating a shift from positive to negative bending moments or vice versa. To calculate it, you first need to determine the bending moment diagram for the beam under the given loads. The points of contraflexure occur where the bending moment is zero; you can find these points by solving the bending moment equation derived from the beam's loading conditions and boundary conditions. Set the bending moment equation equal to zero and solve for the position along the beam.
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.
The line ( y = 3 ) is a horizontal line. The distance from the point ( (5, 4) ) to this line can be found by calculating the vertical distance between the point and the line. Since the y-coordinate of the point is 4 and the line is at ( y = 3 ), the distance is ( |4 - 3| = 1 ). Therefore, the distance from the point ( (5, 4) ) to the line ( y = 3 ) is 1 unit.
In a parabola, the distance from any point on the curve to the focus is equal to the distance from that point to the directrix. If the distance from the green point on the parabola to the focus is 7, then the distance from the green point to the directrix is also 7. Therefore, the distance from the green point to the directrix is 7.
The length of a pendulum can be found by measuring the distance from the point of suspension to the center of mass of the pendulum bob. This distance is known as the length of the pendulum.
It the point is on the line the distance is 0. If the point is not on the line, then it is possible to draw a unique line from the point to the line which is perpendicular to the line. The distance from the point to the line is the distance along this perpendicular to the line.
