What is a deflection plot?

What is a deflection plot?

In essence, the deflection profiles indicate the variation in the measured deflections along the pavement section. The plot is useful for identifying weak locations, erroneous measurements and for selecting test locations or segments for analysis.

Is deflection negative or positive?

Deflection is negative from the world-view but positive from the view of the force.

What does negative deflection mean?

A wave of depolarization traveling away from a positive electrode results in a negative deflection. A wave of repolarization traveling toward a positive electrode results in a negative deflection.

Where does maximum deflection occur in a beam?

For cantilevered beams, the maximum deflection will occur when the load is located at the free end of the beam, while for simply supported beams, maximum deflection will occur when the load is located in the center of the beam.

What is direction of deflection?

A positive charge, top, moving perpendicularly through a magnetic field is deflected. The right-hand rule, bottom, predicts the direction in which the positive charge will be deflected. A similar left-hand rule predicts the deflection of negative charges.

What is load deflection rate?

The load deflection rate (LDR) is defined as the external loading needed for the unit deformation and, in orthodontics, signifies the force generated by the unit length deformation. Orthodontic arch wires with high LDR not only apply excessive force on teeth, but their strength decreases quickly with tooth movement.

How to calculate the deflection of a beam?

I have a formula to compute the deflection of a beam. When I have computed the deflection I get a vector with non-negative elements representing the deflection in each position on the beam. When I am plotting the deflection vector I get a downwards parabola since the elements are positive.

Which is the slope of the deflection curve?

 The right end of the beam is supported by a fixed end support therefore the slope of the deflection curve is 0 and the deflection is 0 EI dv dx

What kind of support resists displacement and slope?

“ Supports which resist a force, such as a pin, restrict displacement “ Supports which resist a moment, such as a fixed end support, resist displacement and rotation or slope 5 Beam Deflection by Integration The Elastic Curve 6 Beam Deflection by Integration 14 January 2011 4 The Elastic Curve 7 Beam Deflection by Integration

Why are the deflections shown in a positive direction?

It sounds like the calculations that you have done yourself (all positive) are shown for a force also in the positive direction. This makes sense logically. The deflections shown in the graph that you attached (all negative) may be in a different coordinate system where the force is acting in the negative direction.
