its 180 degrees
If you use the above answer the conduit will flatten and close off.
The maximum degrees for a single bend in conduit is 90 degrees. Also code only allows four 90 degree bends in a conduit run between pull boxes.

When should you use conduit bends?
You should use conduit bends when you want to bend a pipe to any angle, either 90 or 30 degree angles. To achieve this, you need to master the maths formulas for bending conduit.
What size conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.
Can you use PVC conduit underground?
PVC conduit is recommended for underground installations. Just remember that a ground wire equal to the maximum load current of the device connected at the other end has to be installed. This ground wire is not counted in conduit fill calculations. It has to have a green insulation in colour and be of a continuous length.
What degrees in the equator is solar maximum?
Solar maximum can occur up to 42 degrees north of the equator as it did in 1859.
What is the maximum number of 90 degree bends which should be used in a run of conduit between points where the wire can be pulled?
Per national electrical code you are only allowed 360 degrees which is 4, 90 degree bends before having to use a pull box or termination.
What is the Maximum bending radius for sheet metal forming?
I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
What is the maximum degree of bends allowed for 1 inch emt?
All conduit shall not have more than 360 degrees for it's length between either a box, cabinet, or conduit body. Couplings count as a continuation of conduit.
What are the methods of bending plastic conduit?
The first step is to place a spring inside the conduit thereby preventing it from snapping
What is the multiplier for 45 degree offset in conduit bending?
Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.
When should you use conduit bends?
You should use conduit bends when you want to bend a pipe to any angle, either 90 or 30 degree angles. To achieve this, you need to master the maths formulas for bending conduit.
3 examples of maths in an electrician's job?
simple arithmatic such as adding or subtracting fractions from taking measurements. Algebra when doing certain electrical load calculations Right Angle Trigonometry when bending conduit to calculate angle of the bends, degrees of bends, length of hypotenuse which is the two bend points for offsets and saddles. conduit bending CAN be very complex depending on the application such as parallel offsets, multi shot bends, concentric bends, ect.
What temperature is best suited for bending acrylic?
The correct bending temperature is 130 degrees celcious.
What is absolute maximum bending moment?
bending moment varies with the distance & the load carried by the beam. And also there is a hogging behavior and a sagging behavior occurs in the beam. According to the sign convention hogging and sagging bears opposite signs.(- & +). So if we are asked to find the maximum bending moment whether it is sagging or hogging we should consider the maximum value without considering the sign. That value is called maximum absolute bending moment.
Why is the maximum bending moment of a structural member as the point of zero shear?
Shear is the rate at which bending moment changes or shear is its derivative with respect to span. The integral, bending moment, goes through a maximum when shear goes from positive to negative or vice-versa.
How can glass be made useful for purposes such as bending and resisting heat?
Unlike an optical lens, maximum 'bending' occurs closest to, and minimum 'bending' furthest from, the center of a gravitational lens.
A hand-operated conduit bender with a shoe for bending 1-inch EMT can also be used to bend?

What do you mean bu equivalent shear force and equivalent bending moment?
MAXIMUM SHEAR force bending moment is zero shear force change inside is called bending moment
