Not too heavy. It is not the most pleasant thing to carry a heavy tripod all day long no matter how good it is. Naturally, the best lightweight travel tripod is quite expensive. The less lightweight the equipment is, the more comfortable it is to carry and cheaper to transport by plane...

According to the previous report, the critical damping ratio of the structure is generally in the range of 0 to 10% [36]. Therefore, the critical damping percentage is set to 3% and the overall structural damping coefficient is 6% [37]. In the dynamic response analysis, the structural ...
How heavy should a travel tripod be? It’s important to have a lightweight tripod for travel, so the usual trade-off between having a stiffer/more stable tripod that is heavier isn’t so relevant. As long as the tripod is strong enough to hold your camera and lens without swaying, try...
The most successful example of the conversion mechanism is the spin Hall effect for nonmagnetic metals containing heavy atoms3,4,5,6. For two-dimensional electron gases at Rashba interfaces and the surfaces or interfaces of topological insulators, the charge-to-spin conversion is usually named the...

There exists a critical damping coefficient 𝑐̃=0.275c˜=0.275 for triggering self-excited oscillation. Figure 9. The effect of painting stretch on self-excited oscillation for 𝐼̃=0.3I˜=0.3, 𝑘̃=5.8k˜=5.8, 𝛼=0.35α=0.35, 𝑔̃=1.2g˜=1.2, 𝑐̃=0.27c...
No lightweight armor structure can protect using the same techniques as the heavy armored vehicles. Just as a man with a bamboo stick can deflect a sword if he hits it on the side, so can a lightweight flexible structure deflect the jet stream with forces perpendicular to its travel traject...
Here we improve the light–matter interaction by engineering thin films to exploit relativistic spin–orbit torques that are confined to the interfaces of heavy metal/ferromagnet heterostructures. We are able to excite spin-wave modes with frequencies of up to 0.6 THz and wavelengths as short ...
