STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_C = ((12.5*M'max)-(2.5*M'max+4*M_B+3*M_A))/3 --> ((12.5*50.01)-(2.5*50.01+4*50.02+3*30))/3

Evaluating ... ...

M_C = 70.0066666666667

STEP 3: Convert Result to Output's Unit

70.0066666666667 Newton Meter --> No Conversion Required

FINAL ANSWER

70.0066666666667 ≈ 70.00667 Newton Meter <-- Moment at Three-quarter Point

Define Moment

The Moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. A moment is due to a force not having an equal and opposite force directly along its line of action.

What does Unbraced length mean?

The distance between ends of a structural member (such as a column) which are prevented from moving normal to the axis of the member, by bracing, by floor slabs, etc
