Thank you very much for your teaching.❤

[@shrinivasrao1734]

Thanks these are what we students need lots of problems with awesome solutions like these and practicing

[@n00bOwnZ]

you are the best thx alot for ur help mate !

[@moisesmishan7269]

You are a savior

Is there any chance you could do problems 4-71, 4-104, 4-121, 4-150, and 4-151 from the Statics 14 edition By Hibbler? If not, could you do problems similar to those please?

[@wwatchhthiss]

isnt it that the Fy value should already be in negative?? because the direction of the force is going down. so it should be in negative. plugging it in the summation of forces should be -(-60)...right??? correct me if im wrong.

[@eugenerazo208]

Why fy is not negative when it goes downward? Is it unecessary to consider?

[@independent790]

Why isn't it (-60*5)-(-80*2) for an answer of -140?

Can you do the problem F3-1 using 3KN, 0,15m, 1,5m,30 degrees and 20 degrees . Thank you

I just want to know, how to it is positive or negative

[@adrianogonzales8169]

Spanish, SENTIDO HORARIO O ANTIHORARIO

[@siyabongainnocent7234]

It depends what your lecturer prefers as to refer clockwise negative or positive
Same for anticlockwise

[@nezarayoub7670]

I still didn't get how you change the sign to negative

[@f4th14]

it's because when the force hits it, it moves clockwise and clockwise direction is regarded as negative (wheras counter-clockwise is positive)

[@rupalisutar7261]

Same issue

[@antiquarian1773]

@@f4th14 thanks !

[@Fxyv]

@@f4th14 how come he used signed it counterclockwise first. when the rotation is clockwise

[@f4th14]

Alex Morales wdym signed it counterclockwise first? As in the symbol before the sum of moment (sigma Mo)? That’s just marking the sign convention which he’ll be using (in this case, counterclockwise is positive)
