Practice using the equation converting torque and RPM to horsepower. Do this by converting a given torque and RPM to that of horsepower. A torque of 120 lb × ft is applied so that a car’s drive shaft rotates at 3600 RPM. The horsepower delivered from the engine so that the shaft can...
calculate the gear ratio as 40/20, which simplifies to 2/1, or 2:1. (The tooth count on the driven wheel always goes on top of the fraction or first in the ratio). This tells you that, for every rotation of the driven wheel, the driver wheel makes two rotations. Similarly, a rat...
Remember the torque is how much “muscle” it takes to rotate a mechanism, and comes from three different sources: 1. Accelerating the mechanism’s inertia, 2. Friction, 3. External forces such as pressing against an object or gravity. This is the most difficult part to calculate accurately...
This system transmits power to the rear wheel via a drive shaft. Shaft drives are popular because they are convenient and don't require as much maintenance as chain-based systems. However, shaft drives are heavier and sometimes cause unwanted motion, called shaft jacking, in the rear of the...
The first step is to calculate the spindle speed before the feed rate can be calculated. The second step is to calculate the feed rate. IPM = CPT x N x RPM = 0.005 x 2 x 2,400 = 24 Therefore, the RPM for a l/2-inch-diameter end mill machining aluminum revolves at 2,400 RPM...

The transmission transmits power from the flywheel and directs it, through a driveshaft, to the wheels. The transmission has different gears— or speeds— to control how fast the wheels turn. As the wheels turn, they cause the car to move. To measure the speed of a car, one must be ...
- Load capacity - Calculate radial, axial, and moment loads to choose appropriate load rating. - Shaft size - Ensure proper fit between inner ring bore and shaft dimensions. - Speeds and speeds - Select suitable dynamic and static load ratings for operating rpm. ...
How to Calculate Drill Speed Speed refers to the revolutions per minute (RPM) of the drilling machine spindle. For drilling, the spindle should rotate at a set speed that is selected for the material being drilled. Correct speeds are essential for satisfactory drilling. The speed at which a ...
As long as the comparator switching threshold is faster than the max signal frequency, using only comparators to calculate the position of the motor shaft is feasible. The max switching frequency of a comparator is defined as: (2) It is important to note that the propagation delay can vary ...
