1. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

Why do i need to refer all signals to the output, if i refer them to the output then i wont have any equasions for the input and i wont be able to calculate Y/V
2. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

But i need to write Y(output)/V(input) function, these equasions are very confusing. Y= fN = (F(p+r))N = F(P(z+m+f)+ROv) p=P(z+m+f) r = Ro=ROv b = Bo=BOv o = Ov f = F(p+r) m = M(b-a) a = A ??? z = Z ??? Can you please show me the solution for a and z, thank you, this methodical way is quite...
3. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

How do i write equasion for output then, even if i wrote for a correctly, i cannot resolve for output signal n = N * y, its only one equasion
4. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

I don't understand methodical way, can you please correct me if i am wrong. Thank you.
5. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

I'm thinking about steps for solving this step analytically but i dont really know the othher equasions in order to calculate output/input here are the equasions that i was given
6. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

I have solved this problem, but i dont know if it is correct, can you please tell me if i am right. Thanks for support.
7. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

Here is my attempt for trying to solve TF analitically, i dokt know what to do after that second sumator.
8. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

Here is the example solved analitically
9. ### Engineering Electrical and Control Engineering: Transfer Function Reduction problem

I know how to solve this problem grafically, but this problem i need to solve analitically, without reducing loops.

11. ### Change of angle if refractive index changes for 10^-6

I solved it, thanks for your help !
12. ### Change of angle if refractive index changes for 10^-6

Yes, i know how to take the diferentials, but there is no equasion to diferentiate or i dont know it.
13. ### Change of angle if refractive index changes for 10^-6

Yes i know the solution, but i don't know the steps.
14. ### Change of angle if refractive index changes for 10^-6

Solution: (delta (ϑ)) = -(minus delta n) /(n*sqrt((n^2-1)))
15. ### Average force and angle, collision problem

Ok, solved. Thank you very much for assistance. Mark
16. ### Average force and angle, collision problem

So we are searching horizontal angle of the FORCE
17. ### Average force and angle, collision problem

Right, alfa is 30 degrees, i will just check if its right now
18. ### Average force and angle, collision problem

Ok, i will send you my thinking for this example.
19. ### Average force and angle, collision problem

Yes, of course im solving it analitically.
20. ### Average force and angle, collision problem

Solution is incorrect for angle and force then
21. ### Average force and angle, collision problem

With what average force and under what angle with respect to the horizontal floor did boy kick the ball if the collision took 0.1 second?

23. ### Average force and angle, collision problem

I saw some trigonometric identity for this problem but i don't understand it geometrically, any idea?
24. ### Average force and angle, collision problem

m = 0.1 kg v0 = 10 m/s (x) direction Refractive angle of ball = 30 ° (horizontal) That's the angle of impact. Range of ball = 20 m time of impulse = 0.1 s We are searching for: 1. Angle when the ball was kicked with respect to horizontal. 2. Average force of change in momentum. Solution for...
25. ### Average force and angle, collision problem

No α ≠ 0, but we are searching for α. α= ?
26. ### Average force and angle, collision problem

No α ≠ 30°, β = 30°
27. ### Average force and angle, collision problem

Probably i need to solve for α first. But because velocity 1 changes both x and y components because of average force i don't find a solution.
28. ### Average force and angle, collision problem

Homework Statement [/B] Ball with a mass of 0.1 kg travels at a speed of 10 m /s to the boy. Boy kicks the ball with foot so that it bounces back at an angle of 30 degrees with respect to the horizontal floor. The ball falls back to the ground 20 meters from the boy. With what average force...
