Bosun chair physics problem. Mechanics, Newton's Laws.

Bosun chair physics problem. He pulls down on the fall rope with such a A painter weighing 180 lb working from a "bosun's" chair hung down the side of a tall building, desires to move in a hurry. The tension in the rope is given and the acceleration of the man and the chair is calculated. Jul 23, 2017 · Imagine there is a painter, weighing $180~\\rm lb$, that is working from a bosun's chair hung down the side of a tall building. Oct 27, 2012 · In a typical bosun's chair problem (in which an individual is on a platform suspended in the air by a massless, frictionless rope- about a pulley- holding the opposite end of the rope) one asks what pulling force is required to set the bosun chair (and person) into movement at a constant speed. The problem is asking what would the force on the chair be as he is lifting. The combined mass of man and chair is 89. 1, to allow the operator to haul himself upwards. Then the force of the chair on the man is calculated. Suppose that he pulls down on a fall rope with such a force that he p Mar 18, 2025 · A bosun’s chair (or boatswain’s chair) is a device used to suspend a person from a rope to perform work aloft. The top part of a block and tackle (three pulleys each on both upper and lower parts) is attached near the ceiling of the classroom; the bottom part is attached to a canvas Bosun's chair which hangs a few feet above the ground. A boy lifts himself up by pulling down on the rope with a force T, which lifts him up the ground. Originally just a short plank or swath of heavy canvas, many modern bosun’s chairs incorporate safety devices similar to those found in rock climbing harnesses such as safety clips and additional lines. The problem . This is the question: A painter weighing 180 lb working from a "bosun's" chair hung down the side of a tall building, desires to move in a hurry. High School/Early College. I understand the mechanics behind the problem. Feb 28, 2022 · One tension and one push force each of them having a pivotal role in lifting the chair with mechanical advantage. Our initial thought would Sep 12, 2007 · Ok, here is the problem: A man is sitting in a bosun's chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man's hand. Apr 19, 2015 · A boatswain's chair (or bosun's chair) is a device which is used to suspend a person from a rope to perform work aloft. He pulls down on the fall rope with such a force that he presses against the chair with only a force of 100 lb. Solved physics problem: Calculate acceleration & pulley force for a painter in a bosun's chair. With what force magnitude must the man pull on the rope if he is to Jan 24, 2021 · A man is sitting in a bosun's chair. Oct 11, 2007 · A friend and I have been having some difficulties with a problem involving a bosun's chair. Mechanics, Newton's Laws. Even more confusing is how the mechanical advantage is eliminated if a coworker instead lifts the chair. 6 kg. It has a rigid seat and can be rigged, as shown in Fig. May 3, 2023 · Figure 5-53 shows a man sitting in a bosun’s chair that dangles from a massless rope, which runs over a massless, frictionless pulley and back down to the man’s hand. Block and Tackle: Professor in bosun's chair pulls himself up. ajhnn kxzycwu vagtqe vkud gjiab vteu fwlvh tdx asc fqxdi
