    High School What is the rotation direction of a system with a force applied at point B?

    Let's say the force is applied at point B, you can calculate the moment at point A with the relation : \overrightarrow{M_A}=\overrightarrow{AB} \wedge \overrightarrow{F} Choosing the coordinate system such that x and y are respectively the horizontal and vertical axis, the sign of the z...

    Graduate Continuous and Discrete Fourier Transform at the Nyquist frequency

    Hi there, A quick question concerning the FFT. Let's say I explicitly know a 2D function \tilde{f}\left(\xi_1,\xi_2 \right) in the frequency domain. If I want to know the values of f\left(x_1,x_2 \right) in the time domain at some specific times, I can calculate \tilde{f} at N_jdiscrete...

    Resolved shear stress(rss) problem

    The schmid law allows you to calculate the shear stress as a function of the tensile stress : rss=sigma.cos(phi).cos(lambda) where phi is the angle between the tensile direction and the slip plane normal ([110] in your case) and lambda is the angle between the tensile direction and the slip...
