Why it is easier to lift the same load by using three -pulley system than two-pulley system?
A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.

Which are types of pulley system gives us the maximum mechanical advantage?
A system with three or more pulleys would provide the maximum mechanical advantage. As the number of pulleys increases, the mechanical advantage also increases, making it easier to lift heavy loads.
What are the three forces that act on a pulley system?
The forces that could occur in a pulley system are the force of gravity (due to the pulley's own weight), the tension force (of the rope), and the applied force (the force pulling on the ropes, i.e. a person pulling on it, or a load on the rope). goog dkjf ikjhrknj mjbnrgje gjknhdk irhfgt n s
How much faster will 3 pulley with a belt and one of them is a small pulley will spin?
When using three pulleys with a belt where one of them is a small pulley, the small pulley will spin faster compared to the others. This is due to the principle of rotational speed being inversely proportional to the radius of the pulley. The small pulley has a smaller radius, so it will rotate faster than the larger pulleys in the system.
What are the three parts of a pulley?
The three parts of a pulley are the wheel, the axle, and the rope or cable that runs over the wheel. The wheel is the round disc that rotates on the axle, the axle is the central rod that the wheel spins on, and the rope or cable is what is pulled to move objects.
How does increasing the number of pulleys affect the ideal mechanical advantage and efficiency of pulley system?
Ideal mechanical advantage is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load.The MA of a pulley is equal to the number of supporting ropes.If the load is supported by one rope , the M.A of the system is 1. Efficiency is 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by two ropes , the M.A of the system is 2. But Efficiency is still 1 for ideal pulley ( No loss of energy due to friction)If the load is supported by three ropes , the M.A of the system is 3. Efficiency is still 1 for ideal pulley ( No loss of energy due to friction) .And so on.Read more: How_does_increasing_the_load_affect_the_ideal_mechanical_advantages_and_efficiency_of_a_pulley_system

What is the easier way to get the pulley off a 97 Buick Riviera supercharger?
There is no easy way since these are pressed on. You have to use a pulley puller for this. Now the down side is that you will also have to get the pulley pressed on. Your best bet is to just get a nose cone that already has the pulley size that you want on it. Actually to take it off you need a three hole puller AKA a chicken foot, because yes it looks like a chicken foot. you need three 6mm bolts about 4 inch's long there should three holes in the face of the pulley. to put it back on just insert the crank bolt and tighten, it will go back on easy.

What causes the tensioner pulley to go bad?
There are three sources to belt tensioner failure. The first is through routine wear and tear of the drive system, which is inevitable. Other failure include failure of the pulley bearing resulting in noise, and weakening of the spring loaded assembly itself.

List three advantages an ATX system has over a Baby AT system?
adding and removing components easier, better support for I/O devises and processor technology, lowering costs.
What are the three kinds of pulley?
The three types of pulleys are fixed pulley, movable pulley, and compound pulley. Fixed pulleys are attached to a stationary object, movable pulleys move along with the load, and compound pulleys combine both fixed and movable pulleys to provide mechanical advantage.
What are three reasons a pulley is useful?
A pulley can change the direction of a force, which can make lifting heavy objects easier by allowing the force to be applied in a more convenient direction. It can also be used to lift objects higher by providing a mechanical advantage through multiple pulleys. Additionally, pulleys can be used to transmit power and change the speed or torque of rotating machines.
