determine the magnitude of the force F to prevent the pole from rotating

If the man at B exerts a force of P = 30 lb on his
rope, determine the magnitude of the force F the man at C
must exert to prevent the pole from rotating, i.e., so the
resultant moment about A of both forces is zero. Get the book: amzn.to/2h3hcFq

Thanks!

Thank you!

Nice sum

[@roronoazoro957]

how to to differentiate on using cos or sin?

[@believer..00]

Thank u sir

[@michealrobert2400]

How did you get Fx as 4/5F

[@Maryam-cd1bq]

imagine there is a right triangle F is the hypotenuse=5, to get fx, the side it resembles is the horizontal side of the triangle so fx=4/5.
Same for fy it will equal 3/5 because the y-axis is the vertical side of the triangle. Hope this helps!

thanks Man U da bomb

[@mikeloto21]

question? you mentioned something about Y components of P and the force, could you explain why we don't suppose to use it please

[@zarakjehan7237]

because when we are finding a moment at a certain point then all the forces acting on the same point will be zero like at point A so all the forces directly acting on A is zero

i think im in love with you

[@shrinivasrao1734]

This problems says what moment of force actually is.
