I think if the passing grade is like 60% for example them the final exam have to be at max 50%
having a 70% final exam will make the students slack of the whole course study the very last week all the material to get a passing grade, that would be 8.6/10 in a worst case scenario for them.

Anyone else has this damn problem?
Hi,
I just started an introductory class on Mechanical Vibration and would like to know what's a good book mainly with good problems so i can practice.
To be more clear the topic discussed here ->...
First you calculate the torque you need to lift the bar
Torque=F*d then T=300 * 1.5 = 450 N*m
now you do sum of the torque must be = 0
-450 + 700 *x = 0
solve for x = 0,643
Sorry, power went out on my house.
So it stops acelerating when it touches the spring.
But i still need the energy of the spring right because it touches it?
If i try ep+ek + Eel i get 28 -2v² = 200x²/2
now to find the x
i can use the weight of the ball F=m*a = k *x , i get 40=200*x => x=0,2...
