    Finding z coord. drection angle given x and y coord. direction angle

    I don't really understand what you mean. how would I solve for the vector without having any values to work with?

    Finding z coord. drection angle given x and y coord. direction angle

    Homework Statement The x and y coordinate direction angles of a vector are 50 and 105 degrees, respectively. If the z component of the vector points in the negative z direction, what is the z coordinate direction angle? Homework Equations The Attempt at a Solution I was going to...

    Determine the components of P in the i, j, and k directions.

    There are multiple parts to the question.. I'm only asking about the P vector.

    Determine the components of P in the i, j, and k directions.

    Homework Statement As shown, a pole is subjected to three forces: F, P, and T. The force F expressed in Cartesian vector form is F=[5 i+7 j+6 k] N. Force P has magnitude 7.48 N and acts in the direction given by these direction angles: α=143∘, β=57.7∘, and γ=74.5∘ to the x, y, and z axes...

    Finding the magnitude/direction of a resultant vector?

    Alright, sorry! I did 32.6/sin(r)=15/21.4. I got 21.4 from the calculating the angle 1/2(ThetaB-ThetaA)

    Calculating tension on 3 wires/strings

    alright, i made a right triangle with the x and y being the two sides and the given 90 degrees. it didn't get me anywhere earlier since I didn't have any values. I couldn't figure out how to calculate the values of the horizontal and vertical degrees of the strings, so I went with that triangle...

    Calculating tension on 3 wires/strings

    Homework Statement "a spider is resting after starting to spin its web. The gravitational force on the spider is 0.172 N on the junction of the three strands of silk. The junction is supported by different tension forces in the two strands above it so that the resultant force on the junction...
