Member CB of the vise shown exerts on block B a force P directed along line CB. Knowing that P must have a (1237) N horizontal component, determine (a) the magnitude of the force P, (b) its vertical component

i don't get it what the "N horizontal component"

 

[Frabjous]

N is Newtons.

 

[sHatDowN]

N is Newtons.

horizontal component
i mean this one

 

[kuruman]

Draw force P in the drawing then find its horizontal component.

 

[sHatDowN]

exactly that's my problem what the P force

 

[nasu]

horizontal component
i mean this one

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

 

[kuruman]

exactly that's my problem what the P force

a force P directed along line CB.

Can you draw this?

 

[sHatDowN]

Can you draw this?

is it correct?

 

[Frabjous]

Do you know how to find the horizontal component of P?

 

[sHatDowN]

Do you know how to find the horizontal component of P?

No

 

[jbriggs444]

No

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

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?

 

[sHatDowN]

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?

 

[kuruman]

Try SOH-CAH-TOA.

 

[sHatDowN]

Try SOH-CAH-TOA.

Sorry sir but we don't have any length of p-x or p-y.

 

[sHatDowN]

I find p-x=1013.29 and p-y=709.51
is it correct?

 

[kuruman]

The given value of 1237 N is one of ##P_x##, ##P_y## or ##P##. Which one do you think it is?

 

[sHatDowN]

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 .

 

[kuruman]

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.

[kuruman]

Knowing that P must have a (1237) N horizontal component,

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

 

[sHatDowN]

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

Yes i think.

 

[kuruman]

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.

obviously A

 

[kuruman]

obviously A

Obviously. Now look at my question in post #22 and your answer in post #23.

 

[sHatDowN]

Obviously. Now look at my question in post #22 and your answer in post #23.

Yes Sir Sorry,I was on mistake.

 

[kuruman]

Yes Sir Sorry,I was on mistake.

OK, then fix your mistake and post the correct solution.

 

[sHatDowN]

OK, then fix your mistake and post the correct solution.

 

[kuruman]

That looks correct.

 

[sHatDowN]

then we solved sample problem.
Thanks for your help.
