Yes, checked every solution. If I couldn't solve the problem on my own, I tried to learn from the solution code and if I had additional questions - wrote my problem on stack exchange.
That's why I'm so flabbergasted why I failed.
Hi PeroK,
I took a break for 1year from uni and changed my degree to management. Finished bachelors degree and currently doing masters in Business Informatics. If you need more info, please send me a pm :)
We got only 1 exam = Final exam. Failed this one.
I went to the professor and explained my problem. He just looked at me and said nicely " You have to solve this on your own."
Hi everyone,
Hopefully I'm writing this in the correct part of PhysicsForum.
Here is my problem:
I'm really struggling with my programming class (basics of python3 - loops, dictionaries, numpy).
What I did this semester:
1. Participated in every class
2. Solved everything our course offered...
Hi!
I recently noticed I have really big problems concentrating when attending my college lectures (1year). Let me give an example:
I come to the physics lecture and I'm totally engaged in the lecture material. But after 20min I start to lose interest and I have to physically force myself to...
I checked the torque and I agree there is something wrong, but unfortunately I have to use the given formula (it's mandatory). But I think that in the coefficient C are hidden necessary units.
I suppose that the goal of this problem is to write a homogeneous linear differential formula, but...
Sorry, I meant the rope does not slip on the pulley.
I fixed the last equations and double checked the R-s. But I'm still confused by what you mean with
Torque = moment of inertia times ... what?
The torque in this case is given as a product of C and angular velocity, where C is a factor of...
There is an mass-spring oscillator made of a spring with stiffness k and a block of mass m. The block is affected by a friction given by the equation:
$$F_f = -k_f N tanh(\frac{v}{v_c})$$
##k_f## - friction coefficient
N - normal force
##v_c## - velocity tolerance.
At the time ##t=0s##...
I meant this example:
The correct solution here as well is the dark blue N, because all forces have to cancel out in the diagram.
I was confused because there was a mistake in solution manual and I wanted to be sure if I understand the normal force acting on the rod.
Yes, the rod is hinged at point A.
If there were no hinge and the friction coefficient would be low, then I would conclude that the only force of a wall acting on a rod is perpendicular to a wall ------> blue N.
But this example poses a doubt: the situation is almost similar, only in this case...
