    Dr.Peterson replied to the thread Overlaping triangles.
    So you meant, are there any non-congruent triangles with the same angles and area. I outlined a proof, in explaining why this would be...

    shahar replied to the thread Overlaping triangles.
    Yes I was confused by replacing the word congruent with the word overlapping/ Are there proofs to it?

    Dr.Peterson replied to the thread Overlaping triangles.
    I'm not sure what you mean by "overlapping"; but if you know the three angles, then the shape is determined, and then the area will...

    logistic_guy replied to the thread steel I-beam.
    To warm up the audience, we write the relation between moment and load. M = -\frac{P}{4\beta}f_3(\beta_x)

    If I have 3 angles and an area that is constant number, can I create different triangle with them that aren't overlapping?

    logistic_guy replied to the thread cylinder.
    This problem can be solved by the tangential stress formula. The formula for the internal pressure will be a little different than the...

    logistic_guy replied to the thread steel shaft.
    This problem can be solved by the torsion formula. \tau_{\text{max}} = \frac{Tr}{J} where we will treat the average shear stress as...

    logistic_guy replied to the thread steel circular bar.
    We will let the axial loads be along the x-axis, so there is no normal stress along the y-axis. This gives: \sigma_y = 0 And we have...

    logistic_guy replied to the thread steel bar.
    We find the maximum stress from this equation: \frac{\sigma_{\text{max}}}{\sigma_n} = K

    I am trying to find a percentage to use as an estimation for a rough idea of how many people in a city would sign up for a dance cardio...

    logistic_guy replied to the thread strain fields.
    To solve this problem, we start by introducing the two-dimensional strain matrix. \begin{bmatrix}\varepsilon_x & \frac{1}{2}\gamma_{xy}...

    logistic_guy replied to the thread prismatic bars.
    The idea of this exercise is to calculate the axial load P using two different equations. They will yield different results. The largest...
