You don't know that it's equal zero when your doing the question though.....so why did you assume its zero? ......:D I'm sorry but I'm having a hard time comprehending this shizzle.......Um like I have question all over the place, why - in front? Why are you adding stuff lol...
ok first of all lol i don't know what "point of application" is exactly. And I don't know how to draw the diagram your talking about. I don't know what i'm adding I'm confused lol......In my answer I had a right triangle with the force 375 going in the same way as the tension force.
I've had a bit of a problem with the following question. I have the answer I did it properly except for one part i can't comprehend.
A steel wire 40m long is suspended between two fixed points 20m apart. A force of 375N pulls the wire down at a point 15m from one end of the wire. State the...
Sorry but I'm still not clear on that. I know that to find a value thats divisible in an equation you try f(x) and if that equals 0 in the equation its divisible. In my case its x^3+5x^2+6x+11 so the only things i try are the last number 11. (+-1, +-11) and that doesn't equal 0..........Explain...
Calculating charge and force of electric repulsion
Calculate the force of electric repulsion between two small spheres placed 1m apart if each has a deficit of 1x10^8 electrons.
I tried this and only got r=1m and N=1x10^8
I don't know the equation needed for this please help..
or maybe ur right .....thats the plane......but not the answer
I'm not sure how to find the normal.....(1,0,0)cross what? to get a normal.....then after that put the (x,y,z) values in the equation Ax+By+Cz+D=0
Then find D by inserting the point (4,-2,1) and you've got the equation?
hallsofivy.....that is not the answer.......I think you are wrong.......can you please make it a bit more clear on the steps made to get the answer.
for my first question ok sorry maybe I worded it wrong....how do i find a normal plane of a direction vector in 3 space?
