Right-hand rule for cross product. The cross product of vectors and is a vector perpendicular to the plane spanned by and with the direction given by the right-hand rule: If you put the index of your right hand on and the middle finger on , then the thumb points in the direction of .

Traversal using right-hand rule (). One effective rule for traversing mazes is the Hand On Wall Rule, also known as either the left-hand rule or the right-hand rule.If the maze is simply connected, that is, all its walls are connected together or to the maze's outer boundary, then by keeping one hand in contact with one wall of the maze the solver is guaranteed not to get lost and will reach a ...
A British zebra crossing. The British Government's Road Research Laboratory's (RRL) Traffic and Safety Division was established at Langley, near Slough in 1946. [1]: 2 The division was soon tasked with developing a new type of pedestrian crossing that would be visible in all weather conditions. [2]
Get more zebras in the gallery below: Keep in mind, though, that where zebras live it has an affect on their stripes. Those in warmer climates have more stripes -- which is great for the ...
The placement of objects like pens and gearshifts is also typically geared toward those with a dominant right hand. Here are 19 simple, daily tasks or experiences that can be a hassle for left ...
Using the right hand rule to find the direction of the magnetic field. The direction of the magnetic field at a point, the direction of the arrowheads on the magnetic field lines, which is the direction that the "north pole" of the compass needle points, can be found from the current by the right-hand rule.
There is also a Fleming's left-hand rule (for electric motors). The appropriately handed rule can be recalled from the letter "g", which is in "right" and "generator". These mnemonics are named after British engineer John Ambrose Fleming, who invented them. An equivalent version of Fleming's right-hand rule is the left-hand palm rule. [2]
where u R is a unit vector pointing from the axis of rotation to one of the spheres, and Ω is a vector representing the angular rotation, with magnitude ω and direction normal to the plane of rotation given by the right-hand rule, m is the mass of the ball, and R is the distance from the axis of rotation to the spheres (the magnitude of the ...
