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 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
