1. 2 EK

2. Modulus of Elasticity

3. The value of moment to be applied to that end to cause a local slope of one radian.

4. The ratio of the moment produced at the far end to the applied moment at that support end.

Carry over factor is defined as the ratio of the induced moment to the applied moment. It is always for members of the constant moment of inertia. The carry over factor is zero if the end is hinged/pin connected.

## Answer: The ratio of the moment produced at the far end to the applied moment at that support end.

The carry over factor is not half and is different for both ends in the case of the beams with variable moment of inertia. It is also known as a developed moment or induced moment. The carry over factor is given by: Carry over factor = Carry over moment / Applied moment.

### Other Important Factors

The other important factors in the moment distribution method are:

1. Relative stiffness or stiffness factor

2. Distribution moment and distribution factor

Stiffness Factor: The moment that must be applied at one end of a constant section member to produce a unit rotation of that end when the other end is fixed is the stiffness factor.

Distribution Factor: It is the ratio of stiffness of a member to the sum of the stiffness of all members at that joint.

Summary:

## Carry over factor at a support/end is defined as

Out of the given options, the correct answer is ‘The ratio of the moment produced at the far end to the applied moment at that support end’.
