Vector problem, magnitude of the force

In summary, the conversation discusses determining the magnitude and components of a force P directed along line CB. The horizontal component is given as 1237 N and can be found using the SOH-CAH-TOA formula. The conversation includes a drawing of a right triangle with P as the hypotenuse and the horizontal and vertical components labeled as Px and Py. The correct solution is found and the conversation ends with a thank you for the help.

horizontal component
i mean this one
 
  • #4
Draw force P in the drawing then find its horizontal component.

The horizntal component is given as 1237 N. "N" is the unit for force in SI, newton.

Can you draw this?

Can you draw a right triangle with P as the hypotenuse where the other two sides are vertical (label this one Py) and horizontal (label this one Px)?

Can you label the hypotenuse as P?

What are the three angles for this triangle? Can you fill in those measures on the drawing?

If you wanted to know the length of ##P_x## and you knew the length of the hypotenuse ##P##, can you think of a useful formula?

Sorry sir but we don't have any length of p-x or p-y.
 
  • #17
I find p-x=1013.29 and p-y=709.51
is it correct?
 
  • #18
The given value of 1237 N is one of ##P_x##, ##P_y## or ##P##. Which one do you think it is?

Yes sorry sir i find out please check .

I don't understand what you mean by this. Please post a drawing of the triangle like you have in post #14 with the label 1237 N next to the side that you think corresponds to it.

Is what you have labeled with 1237 N the horizontal component of P?

Yes i think.

Below is a picture of the horizon. Which line do you think best describes the horizontal direction?

(A) From left to right.
(B) From top to bottom.
(C) From top left corner to bottom right corner.
