Is it possible to swing on a whip

Let me draw the forces on the swinger at the bottom of the swing. Yes, the swinger is indeed accelerating at the bottom of the swing. Because the person is moving in a circle and changing direction. The acceleration is directed towards the center of the circle in this case that's up and the magnitude of the acceleration depends on the velocity and the radius of the circle which happens to be be L. In order to have an upwards acceleration, you need a net force that's up. Since there is only the whip and gravity pulling on the person, I can write:.

That's it. I just need values for the length of the whip, the mass of the person and the starting angle. Putting these values in, I get a whip tension of Newtons.

This is 1. Of course this is probably much greater than the tension from just pulling on the whip before the swing. Is this why the whip slipped off the log during a few swings? Now that you have seen how to solve some of these homework problems, here are some more for you to consider. How do you swing a 5, lb wrecking ball? In the Simpsons episode, the MythBusters wanted to swing a wrecking ball into a house.

As they state in the show, this isn't such an easy task. The crane operator stated that based on the mass of the ball, they could only pull it back 12 feet before letting go.

Here is the question. If the ball can only be pulled back 12 feet, would it be better to have a shorter cable or a longer cable? I am assuming the 12 ft distance doesn't depend on the length of the cable. I'm, not just going to give you a silly diagram and then leave you alone. Nope, I am going to give you even more help. Check this out.

That is a numerical model of a swinging wrecking ball. Here is the code in GlowScript so that you can run it yourself and change things around.

I hope that made sense. For many knots, the harder you pull the more they tighten. Failure comes when the rope breaks typically just outside the knot , not when friction is overcome. The principle is the same. Even a simple wrapped whip is quite difficult to analyse. The weight of the free-hanging end not the end you hold onto- the other one sets the limit of the tension at the end of the coil, while your weight plus a bit for the swing sets the tension at the beginning of the coil, and the coil itself is trying to contract onto the shaft.

If, after snapping your coil around the shaft, you flip a wave up the whip so that the first coil now lies atop of the others, you have something that may indeed behave like a knot, and the game changes. If you advance frame by frame when the Treacherous Assistant makes his swing back across the pit, you can see that the end of the last coil has helpfully slipped itself under one of the others, forming a veritable knot - a single hitch.

This is no mean feat, and nicely demonstrates why Indy is Indy and the rest of us mortals are just not worthy! If anybody could do it, I think it would be me. My last name is Jones, and I once whipped a chip put of someones hand.

I also used a rolled up measuring tape as a whip and whipped the milk out of my sisters spoon as she was bringing it towards her face to eat her cereal. Now who is gonna top that??? Have any of you whip-wielding Dopers ever hit yourself with your whip strike? If so, what did it feel like? The trick to doing a whip swing is, after you do the wrap, you wanna flick the whip over the wrap, so the whip is overlapping the wrap which creates a sort of lock, at which point you can swing to where ever you need to go.

If youre going to use a Roo hide whip to swing, you want to use at least a 10 plait whip, the higher plait amount, the stronger the whip. The idea seems doable, after all this is how hitching posts work for horses.
