10-speed bicycle cassette. On a bicycle, the cassette or cluster [1] is the set of multiple sprockets that attaches to the hub on the rear wheel.A cogset works with a rear derailleur to provide multiple gear ratios to the rider.
the number of possible gear ratios is 24 (=3×8, this is the number usually quoted in advertisements); the number of usable gear ratios is 22; the number of distinct gear ratios is typically 16 to 18. The combination of 3 chainrings and an 8-sprocket cogset does not result in 24 usable gear ratios.
The sprocket wheels a, b, and c engage and transport the film. a and b move with uniform velocity and c indexes each frame of the film into place for projection. Sprockets are used in the film transport mechanisms of movie projectors and movie cameras. [5] In this case, the sprocket wheels engage film perforations in the film stock.
Two intermeshing spur gears rotating at different velocity due to differing gear ratio. A gear [1] [2] or gearwheel [3] [4] [5] is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part.
The use of bevel gears allows the axis of the drive torque from the pedals to be turned through 90 degrees. The drive shaft then has another bevel gear near the rear wheel hub which meshes with a bevel gear on the hub where the rear sprocket would be on a conventional bike, and canceling out the first drive torque change of axis.

SACO (Saudi Company for Hardware) is a provider of home improvement products in Saudi Arabia. Founded in 1984, SACO started out with one store in Riyadh.Over the next two decades, the company expanded its reach across the country and, to date, operates 34 stores in 18 cities, including five stores (known as SACO World), each occupying between 2,350 and 24,500 square meters.
Location of Saudi Arabia. Saudi Arabia is a sovereign Arab state in Western Asia constituting the bulk of the Arabian Peninsula. The country's command economy is petroleum-based but slowly diversifying; in 2017 58% of budget revenues and 85% of export earnings came from the oil industry.
