I tried 3 ways and I still don't get a good curve.

That's what I did. Rearrange the first equation A=sqrt(2^2+5^2-2(2)(5)cosθ) sinφ/5 = sinθ/A to isolate sin(phi) φ=arcsin[(5sin(θ)/A)] should there be a parenthesis between 5 and sin? plug that into F/W = cos(theta)/sin(phi) F/W = cosθ/sinφ Unless I'm typing it wrong in excel A2=5...

You mean just go directly with F/W = cos θ/sinφ and leave out this... Plug in θ and get A A^2=2^2+5^2-2(2)(5)cosθ Then I'll plug in both θ and A to get Phi. φ=arcsin[(5sin(θ)/A)] If so, where would I get phi from if I'm only starting with θ?

I'm suppose to plug all of this into excel and make a plot with a line curving with θ being between 5 ≤ θ ≤ 60 degrees. My idea was this: Plug in θ and get A A^2=2^2+5^2-2(2)(5)cosθ Then I'll plug in both θ and A to get Phi. φ=arcsin[(5sin(θ)/A)] Then I'll plug θ and φ F/W = cos θ/sinφ But...

My plot didn't come out correctly, so I know I did it wrong. Where did I go wrong or was I even close? 1. Homework Statement The hydraulic car lift shown in Fig 1 will be used to lift a vehicle of weight W. Determine the force in the hydraulic actuator required support the vehicle as a...

I have to create a formula where one would just need to input y to get the tension from CD. 1. Homework Statement A worker plans to lift a 60-lb 5 gallon bucket of paint by tying a rope to the scaffold a A and then passing the rope through the bail of the bucket at B and finally over the...

Homework Statement Write down the intensity equation for a two-slit interference pattern with diffraction effects included. Indicate which part originates from double-slit interference and which part from single-slit diffraction. What happens when the angle = 0Homework Equations...

Thanks. The answer was already given to me in a different forum.

Are these answers correct? What is the true frequency of the uncalibrated generator? The true frequency of the uncalibrated generator is 904 Hz. Is there more than one possibility? Yes. The uncalibrated generator could be 866 Hz,

Beats frequency happens when two different waves are at a point with the same amplitude. A calibrated wave generator has a wave as a standard and an uncalibrated wave generated is not similar to the calibrated wave.

Imagine that you have a calibrated sine wave generator set at 900 Hz and you mix its signal with that of an uncalibrated generator also set at 900 Hz. You hear a beat frequency of 4 Hz. What is the true frequency of the uncalibrated generator? Is there more than one possibility? I'm...
