The straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

Before calculating ... along the line from left to right, you would be walking downhill, so the gradient will be negative. Then, choosing two random points on the line and using the same method ...

The stress–strain behaviors of viscoelastic materials are often simulated using ... equation, the derivation of the constitutive equation is transformed into operations involving the incidence matrix ...
