As rock climbers ascend El Capitan over the course of 2 or 3 days, they have to bring all their food, water and camping equipment with them. All of this gear gets put in a large heavy duty bag and is hauled up after each section (called a pitch) that they climb. Climbers will generally climb a 50m pitch then stop and set up a pulley system to haul up the bag. If the rope has a mass of 0.05 kg per meter, the bag of gear has a mass 20kg and the rope is 50m long, how much work (in N-m) is required to pull up all the rope plus the haul bag?
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.
