    Undergrad Kinetic equation of gases: time between collisions instead of time of colission?

    And can it be done differently?

    I understand everything except why do we use time between collisions instead of time of colission?

    Calculate the stresses in this 4-member wooden frame

    I already knowed how to solve those problems but that confused me. That is first time I needed to know that forces are parallel.

    Calculate the stresses in this 4-member wooden frame

    I tried to solve it without assuming that forces are parallel, but failed. I beleaved that it is true but i wanted to see that proof.

    No. I just need proof 😂

    Calculate the stresses in this 4-member wooden frame

    I think that I proved that forces must be parallel if system is in static.

    Did you solve it?

    Still can't do that.

    I can't send picture now it say that I have low memory

    Calculate the stresses in this 4-member wooden frame

    I brake that in pieces but always get 2 unknowns and 1 equation. That is impossible to solve.

    Calculate the stresses in this 4-member wooden frame

    How ever I tried I did not managed to solve it.

    Calculate the stresses in this 4-member wooden frame

    Can this be solved without assuming that forces are parallel?

    Calculate the stresses in this 4-member wooden frame

    Why force at D need to be parallel to force at E and F?
