To hold the weight in the air you must apply only 25 pounds of force, but to lift the weight 100 feet higher in the air you must now reel in 400 feet of rope. A block and tackle can contain as many pulleys as you like, although at some point the amount of friction in the pulley shafts begins to become a significant source of resistance.
As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant line.
The first major weight reduction will be the front K members, because that would remove weight from the front and effectively add a larger percentage of weight to the rear wheels The last weight reduction for my car will be an aluminum flywheel or driveshaft.

Take the stated motor rpm or measured and simply apply the appropriate ratio to the diameter of the motor pulley to get the speed you want. To make this easier Motor rpm 2000 rpm Motor drive pulley dia. 2 just for sake of argument 2000 rpm, use a 2 driven pulley 11 1000 rpm, use a 4 driven pulley 12
A pulley is a simple machine, and you calculate its mechanical advantage by counting the number of ropes supporting the weight. The pulley load reduction is equal to the reciprocal of the mechanical advantage. The maximum practical load reduction is 14 because few
Using This Pulley and Belt Size Calculator. Enter the motor speed in RPMs. Enter the motor pulley size in inches. Enter the driven Pulley size in inches. Adjust the drive and driven pulley sizes, to achieve a certain RPM output. More than one stages of pulley speeds can be calculated in a compound drive system. The output of the first stage ...

Pulley Weight The total weight of the pulley assembly to be supported by the shaft will impact shaft sizing. Selection of a pulley with robust construction and heavier weight should be accounted for when selecting shaft diameter. Pulley Position The purpose and position of a pulley in the conveyor i.e. Drive, tail, bend, or take-up impacts ...

Ouput Torque Input Torque x Ratio of Gear Reduction. Torque is measured in Inch Pounds. Output Speed Input Speed Ratio of Gear Reduction. Example A gear reducer with 1000 inlbs of input torque, an input speed of 2000 RPM, and a reduction ratio of 3.51 is Output Torque 1000 x
Working Load Limit for Crosby Blocks indicates the maximum load that should be exerted on the block and its connecting fitting. A single sheave block used to change load line direction can be subjected to total loads greatly different from the weight being lifted or pulled.
Mechanical Advantage of a Pulley Calculator. When the small input force applied on a machine increases the magnitude of the output force, it produces mechanical advantage. Pulley is a wheel on a shaft used for the movement of a belt along its circumference. The movement can
we refer to a speed up system if the ratio is 1 ex. 41 , its a speed reduction system. In both cases, the ratio is obtained using the dimensions of the input drive driver pulley and the output driven pulley. In the following ratio, RS is the speed ratio, D1 the diameter of the driver pulley, D2 the diameter of the driven pulley
To make the weight rise 1m, you have to shorten each section of the rope by 1m, so you have to pull the loose end of the rope by 4m. We say a pulley with four wheels and the rope wrapped around like this gives a mechanical advantage of four, which is twice as good as a pulley with two ropes and wheels.
Pulley and belt systems are one of the easiest ways to change speed and torque in a system. If a small pulley is connected to a large pulley and the small pulley is the driver, the large pulley will turn more slowly but with increased torque or rotational force. If the large pulley
