This drive mechanism does not use chaindrive or shaftdrive but has efficiency as chaindrive (in terms of gear teeth engagement) and requires less frequent maintenance. Extra length requirement due to pedals is removed and length of bicycle can be further reduced by using smaller front wheel.
Welding technologies are fundamental to fabrication and ubiquitous within manufacturing. Laser welding has found wide application for the joining of precision metal components and high-speed production due to the intense laser heat source. Low penetration or “conduction mode” welding is well controlled,
Manned aircraft are quite heavy and cumbersome in some areas of aviation use. For example, aerial photography in cartography or forestry, spraying fertilizers or pesticides on medium-sized crop fields. And in these cases, unmanned aerial vehicles are a rational solution.
Drones give more secure, faster,
The main problem of space exploration are the costs due to an obsolete technology after sixty years we are still with liquid thrusters,
The automotive greases have various metal additives to ensure the properties and retention under various extreme working conditions. However, depending on loss of these elements the grease looses its properties.
Problem:
As a mechanical engineer with previous journey of work in different industries of which air pollution is a common factor that necessitates the protection of the workers respiratory tract,
False alarms are a common problem with invisible laser based sensors.
In border areas it just creates panic to identification whether it is a human being, an object, dust, an animal or some vehicle moving across the border.
