AI Thread Summary
To achieve a complete revolution of a pendulum, it must be released from a vertical position, pointing straight up. The length and weight of the bob do not affect this requirement, as the motion is governed by conservation of energy. Neglecting friction is crucial, as any resistance would prevent a full revolution. The initial release angle is the key factor in achieving the desired motion. Therefore, starting the pendulum at the correct angle is essential for a complete revolution.

I need to find the length, weight of the bob and angle to make the pendulum a complete revolution. Kindly help me.

Neglecting friction, a pendulum only swings as high as you initially release it from due to conservation of energy. So if you want a complete revolution, you will have to start the pendulum pointing straight up and get rid of the friction. It does not depend on length or weight.
 


thanks dude.
 

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'

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...
