AI Thread Summary
Earth rotates once every 24 hours, with points on the equator moving at approximately 1,667 km/hr. Despite this high speed, we do not feel it because the atmosphere moves with the planet, creating no relative wind. Additionally, the force of gravity acts vertically downward, maintaining a consistent experience of weight. The effects of inertia further contribute to our inability to perceive this motion. Overall, the combination of these factors explains why we do not feel the Earth's rotation.

Earth is completing one rotation in one day i.e, in 24 hours. Its equator length is around 40,000 km. Every point on equator is moving with a speed of 40,000/24 i.e, 1667 km/hr. Why don't we feel that speed even though we are moving at such high speeds when we are at equator?

We don't get blown over because the air moves with the earth. We weigh a tiny bit less at the equator because of the spin. Gravity continues to act vertically downwards, so we notice no changes in the forces on us because there are no changes in magnitude or direction.
 
Magic effects of inertia :)
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
