GO to the ER IMMEDIATELY! You might require a surgery. I am NOT joking!
The joint between the humerus and the ulna bends the elbow.
You are allowed 4 - 90 degree bends between openings. This is 360 degrees. Regardless of the sizes of bends, the 360 degrees is the limitation. In actual practice, you want to avoid bends as much as possible. I can tell you from experience that having more than 270 degrees, that's 3 - 90 degree bends, is ill advised unless absolutely necessary.
Use these numbers when bending offsets: 10 degree bends, multiply the depth of the offset by 6 this will give you the distance between bends. For 20 degree multiply by 2.6, for 30 degree multiply by 2, for 45 degree multiply by 1.4, for 60 degree multiply by 1.2. I use 30 degree bends for all of my offsets, just because its easier to do the math. So your answer would be 24 inches between bends. I have come to the conclusion anybody can bend conduit, its the measuring and marking that requires skill.

The electrical code states that there will be no more that 4 quarter bends between junction boxes. Keep in mind when conduit bending that an offset of two 45 degree bends is classed as a 90 degree bend. Offsets between two junction boxes uses up two of the four 90 degree bends allowed.In a conduit run between J boxes the number of bends can not exceed 360 degrees.The electrical code allows four 90 degree bends between pull boxes.
There has to be a pull box between every four quarter bends in a conduit run.
Code states no more that 4 - 90 degree bends in a conduit run between pull boxes.
"The bends" is a slang term for Decompression Sickness. When breathing compressed air at high pressures for extended times, nitrogen gas is forced into the blood. When the pressure is released, the dissolved gas appears as bubbles (like the carbon dioxide bubbles in a soda). The bubble accumulate at joints, causing severe pain, making you curl up (bend) In severe cases, the bubbles can damage the brain, causing a stroke- and death.

If in a conduit run, the limit of 90 degree bends is utilized, always pull in stranded wire to make the pull go easier.
Convex when it bends outwards, concave when it bends inwards
Yes, in a way, because of the way that the Scandinavian peninsula bends.
