A load cell (or loadcell) is a transducer which converts force into a measurable electrical output. Although there are many varieties of force sensors, strain gauge load cells are the most commonly used type. Except for certain laboratories where precision mechanical balances are still used, strain gauge load cells dominate the weighing industry.

11.1 Introduction to Bearing Stresses. The stresses developed when two elastic bodies are forced together are termed bearing stresses. They are localized on the surface of the material and may be very high due to the small areas in contact. The design information given in this section assumes either static loading or low velocity loading.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The rate at which the dis- charge takes place is controlled by monitoring the "loss in weight" of the hopper and then modulating the discharge rates to maintain the desired flow rate. The discharge may be ended at the completion of the process step, or when a specific amount of material has been discharged.

Those are the three basic load components on the bearing. We have to consider the weight of the component, the force and the drive forces. In this case it was a belt, but it could be chain driven or gear driven. And then you have the fly bills. If we know the distances, we can use stats to determine the load on the bearing.

The torque meeded to accelerate the system inertia is often larger than the friction torque of the load. This limits how quickly the load can be accelerated. As shown by the following graph: the dynamic torque performance of a stepping motor is constant at low speeds. But at higher speeds, the torque drops as speed increases.

The value of this load angle or coupling angle (as it is called) depends on the amount of load to be met by the motor. In other words, the torque developed by the motor depends on this angle, say, . This angle is referred as load angle or coupling angle. This is also the angle between rotor and stator fields. 7.
