    Pendulum Swing
AI Thread Summary
Jack, weighing 653 N, swings from a 26 m vine, descending 3.2 m from a cliff. The critical question is whether the force on the vine exceeds 950 N, which would cause it to break. Calculations are needed to determine the greatest force experienced by the vine during the swing. The discussion also emphasizes the importance of not double posting in forums. The outcome hinges on the physics of pendulum motion and the forces involved.

Jack, who weighs 653 N, swings from a cliff at the end of a convenient vine that is 26 m long. From the top of the cliff to the bottom of the swing, he descends by 3.2 m. The vine will break if the force on it exceeds 950 N.

(a) Does the vine break? yes / no
(b) What is the greatest force on the vine during the swing? ____Newtons
(c) At what angle does it break, if it breaks?

This should be in the homework section.

What exactly have you done so far?
 
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...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
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...
