# Why cant parallel lines curve or turn?

If it is curving, it's not a line.

### What is the difference in two surge protectors in series vs two in parallel?

Surge protectors in series will limit based on twice the voltage of one surge protector because, implied by Kirchoff's Voltage Law, voltage drop across components in series is additive. Surge protectors in parallel will protect based on twice the current of one surge protector because, implied by Kirchoff's Current Law, current through parallel components is additive. (Yes, I said "protect" instead of "limit" deliberately because this is a different situation.) However, the parallel configuration is…

### A shape that has two parallel sides?

There are many shapes with parallel sides: e.g. most regular quadrilaterals like Squares, Rectangles and Parallelograms have parallel sides, and so do quite a few regular polygon. But what is a parallel side (or line)? These are two line which are exactly the same length apart and must always be straight and consequently will never meet, no matter how far they extend. For example, train tracks are often parallel (until they bend for the train…

### What is a Christie turn in skiing?

A Christie Turn is a combination of a Stem Turn and a Parallel Turn. You start with your skis parallel, skiing downhill, or traversing across the hill. When you want to turn, you put your upper ski into a V position, with the front of your skis pointing together. You will now be 'Snow Plowing'. Once your in this position, you can adjust your weight to inside edge of the outside ski, causing you to…

### Why does your body lean when you are riding on a bike and you turn around a curve?

This is a gyroscope action showing the laws of Hamilton's Vectors IJ=K. Consider the wheel as pointing in the -I direction, when you turn to the wheel around J , the vector action turns around K (parallel to the ground) which causes you to lean. into the turn. Bikers use that action to just lean around K and thsi will turn you around J. just as if you turne d the wheel, -IK = J…
