I am able to solve this easily using energy conservation, but I'm curious how one would go about solving this using forces and torques?
Forces and torques play a crucial role in determining the motion and equilibrium of a pulley system. The force applied to one end of the rope will be transmitted through the pulley to the other end, resulting in a change in direction and magnitude of the applied force. Torques, on the other hand, are responsible for rotating the pulley and causing a change in the rotational motion of the system.
To calculate the tension in a pulley system, you need to consider the forces acting on each end of the rope. The tension in the rope will be equal to the force applied to one end of the rope, which is being transmitted through the pulley to the other end. Additionally, you can use the principle of torque equilibrium to calculate the tension in the rope.
Static equilibrium occurs when all the forces and torques acting on a pulley system are balanced, resulting in no net movement or rotation. On the other hand, dynamic equilibrium occurs when the system is in motion, but the forces and torques acting on it are still balanced, resulting in a constant motion without any acceleration.
The mechanical advantage of a pulley system is determined by dividing the output force (the force applied to the load) by the input force (the force applied to one end of the rope). This ratio will give you the number of times the input force is multiplied to produce the output force. For example, a mechanical advantage of 4 means that the output force is four times larger than the input force.
Yes, a pulley system can have an ideal mechanical advantage, which means that there is no friction present in the system. In an ideal system, all the input force is transferred to the output force without any loss due to friction, resulting in a mechanical advantage equal to the number of pulleys in the system. However, in real-world scenarios, friction is always present, and the mechanical advantage will be slightly lower than the ideal value.
