    [Statics] Determining the normal force at an internal point of a member

    I figured it out. Used a wrong number for the second method causing the answer to differ. Thank you nonetheless.

    [Statics] Determining the normal force at an internal point of a member

    For this problem (see image), I get the correct answer for the normal force at point E if I: 1) divide the frame into members AB and CB, 2) solve for the x and y components of the reaction force at point B, 3) make a free body diagram with the cut at point E forming member EB and setting the sum...

    I Using polar coordinates to describe rose petals

    Wait, I don’t understand, how’d you determine that?

    I Using polar coordinates to describe rose petals

    I encountered a question which asked me to describe the rose petal sketched below in polar coordinates. The complete answer is R = {(r, θ): 0 ≤ r ≤ 6 cos(3θ), 0 ≤ θ ≤ π}. That makes sense to me for the right petal. What about the other two on the left?
