the word pulley device that for easy movement of objects
In a pulley system in equilibrium, the forces acting on the pulley must be balanced. This means that the tension in the rope pulling on each side of the pulley is equal, resulting in a state where the pulley is not moving. This equilibrium condition is reached when the net force acting on the pulley is zero.
the pulley on the harmonic balance drives the alternator belt. this is the pulley at the bottom of the engine ,on the front of the crank shaft if this pulley is not turning you have a problem. this means either the key is missing or the crankshaft is broken
It means, facing away from the pulley
Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
The velocity ratio of a single fixed pulley is 1. This means that the input and output speeds are equal. The pulley simply changes the direction of the force applied.
Lifting something by artificial means like a pulley.
A big pulley generally lifts an object faster than a small pulley. This is because a big pulley has a larger diameter, which means the object will be lifted a greater distance in each rotation compared to a smaller pulley.
Thew pulley changes the direction of the effort force.
The formula for the mechanical advantage of a pulley system is MA = 2 * (number of support ropes). This means that for every additional support rope, the mechanical advantage of the pulley system doubles.
A wheel with a broad rim, or grooved rim, for transmitting power from, or imparting power to, the different parts of machinery, or for changing the direction of motion, by means of a belt, cord, rope, or chain., To raise or lift by means of a pulley.
A movable pulley reduces the effort force required to lift an object by distributing the force between two sections of the pulley system. This means that you only need to apply half the force compared to a fixed pulley to lift the same load.
The weight of an object is directly proportional to the pulley tension required to lift it. This means that as the weight of the object increases, the tension in the pulley system needed to lift it also increases.
