    How Should Angles Be Used in Calculating Tension Forces?

    I got the right answer! When I solved the first equation for T2, I dropped the T1 and it threw off everything else too.

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    Is the degree in the picture the correct one to use in the equation? Since you have to put in the x and y coordinates; it might be 14 degrees BELOW the x-axis on either side, but the angle is measured counter-clockwise from the positive x-axis. So that's why I'm questioning it. I have the...

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    The sum of the y components would be the 2Tsin(theta). I really just don't know what angle to use for theta.

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    What angle would you use though? And I'm not really sure for the x direction...is it 0? Or is it 2Tcos(theta)?

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    I think I got that part... would you find the x and y components using Tcos(theta) and Tsin(theta) for each one? Do you have to do it for each angle? For the angle, would you do counter clockwise from the x-axis?

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    I don't have a mass or acceleration though...is there a normal force exerted on it?

    Finding equilibrium force when two wires pull at 14 degrees below horizontal

    Homework Statement See the attachment for the diagram and problem: Homework Equations So the magnitude of the tension in the wire is 13.38 N. And each angle is 14 degrees below the x-axis, one on the positive side and one on the negative side. Would I use my Tcos(theta) and...

    How Should Angles Be Used in Calculating Tension Forces?

    Homework Statement See attached figure below for problem: I'm designating the "horizontal cable" T1, the "incline cable" T2, and the "vertical cable" T3. Homework Equations I used the following to find x and y components of each force: x comp=Tncos(theta) y comp=Tnsin(theta) The...

    Finding a plane's weight and horizontal acceleration at takeoff

    So you're saying that the 7959.23 N is my weight of the plane? I guess that would make sense, since it's a constant vertical speed (y direction)...

    Finding a plane's weight and horizontal acceleration at takeoff

    Homework Statement On an airplane's takeoff, the combined action of the air around the engines and wings of an airplane exerts a 8240-N force on the plane, directed upward at an angle of 75.0° above the horizontal. The plane rises with constant velocity in the vertical direction while...

    Two forces applied to car, direction?

    Two forces applied to car, direction?? Homework Statement Here is my given diagram and problem: Homework Equations I'm stuck on finding the direction. I tried using the equation theta=tan^-1(Ay/Ax), and the answer was incorrect. The Attempt at a Solution As you can see, I have...

    Projectile Motion problem Phyisics 1

    Okay, so I'm trying to find the Vx and Vy for 45*. I just used a value for Vi like you said, 10 m/s. Vx=10m/s(cos 45*)=7.071 Vy=10m/s(sin 45*)=7.071 So now I plug those into the respective X(t) and Y(t) equations? What value do I use for the Xi and Yi of them?
