In the American Engineering and Gravitational systems the unit is a cubic foot (ft 3) or more commonly inch 3 Let an area A, of any shape, and division of that area into n number of very small, elemental areas In the American Engineering and Gravitational systems the unit is a cubic foot (ft 3) or more commonly inch 3
Statics Moment in 2D example problem YouTube. The static or statical moment of area, usually denoted by the symbol Q, is a property of a shape that is used to predict its resistance to shear stress. The sign conventions for moment-area theorems are as follows: (1)The tangential deviation of a point \(B\), with respect to a tangent drawn at the elastic curve at a point \(A\), is positive if \(B\) lies above the drawn tangent at \(A\) and negative if it lies below the tangent (see Figure 7.9)
