The key idea is converting rotational speed from revolutions per minute to radians per second and then multiplying by torque to get power. The constant 9.55 is an approximate way to do that conversion, since P = τ × ω and ω = 2π × RPM / 60, so P ≈ (τ × RPM) / 9.55. With τ = 10 N·m and RPM = 100, the calculation is (10 × 100) / 9.55 ≈ 104.7 watts. You can also confirm using the direct ω method: ω = 2π × 100 / 60 ≈ 10.472 rad/s, and P = τ × ω = 10 × 10.472 ≈ 104.72 watts. Both paths give about 104.70 W.

OL on a voltage measurement means the input signal is higher than what the current range can handle. The fix is to switch to a higher voltage range. Digital meters measure voltage by using a resistor divider to scale the unknown voltage down to the ADC’s workable input. If the voltage is too large for the chosen range, you get an overload reading. By selecting a higher range, the meter widens the maximum it can accept, bringing the signal into range and allowing a numeric reading. After switching, aim for a range just above the expected voltage to get better resolution without risking overload. Also ensure you’re measuring the correct type (DC or AC) and that the probes are connected properly. Recalibration or a fresh battery isn’t the remedy for an overload reading.

Automated packaging equipment is built to perform the actions that directly finish a package: wrapping the product, sealing the package, and applying labels for identification and tracking. A crane, on the other hand, is a heavy-lift device used to move and position goods rather than to complete a packaging operation. It isn’t a typical feature of packaging lines, which is why it’s the best choice. Wrappers, sealers, and labelers are standard components because they carry out the core packaging steps: wrap, seal, and label.

A flange bearing combines a bearing with a mounting flange so you can bolt the unit directly to a frame, keeping the shaft axis perpendicular to the mounting surface. This built‑in flange gives a stable, repeatable way to align and secure the bearing, which is essential for maintaining accurate shaft alignment and handling radial loads while making installation and maintenance easier. You’ll see flange bearings used where a roller or shaft needs solid, straightforward mounting to a chassis or machine frame. The other descriptions describe different ideas—no mounting feature, a sealed type, or a different rolling element arrangement—none of which capture the defining flange that enables such mounting.
