If a car goes through a curve too fast, the car tends to slide out of the curve. for a banked curve with friction, a frictional force acts on a fast car to oppose the tendency to slide out of the curve; the frictional is directed down the bank (in the direction water would drain). consider a circular curve of radius r = 200 m and bank angle (theta), where the coefficient of static friction between tires and pavement is (mu-static). a car (without negative lift) is driven around the curve as shown in the diagram. (a) find an expression for the speed vmax that puts the car on the verge of sliding out. (b) on the same graph, plot vmax versus angle (theta) for the range of 0 degrees to 50 degrees, first for (mu-static) = 0.050. (now i hope you can see why accidents occur in highway curves when icy conditions are not obvious to drivers, who tend to drive at normal speeds.

answer: a ball

explanation: because it will bounce

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).

the answer is a 3.8cm
