Qudratic equation for bending point
I have completed an assignment but for this 1 question, any help would be appreciated
In construction it is important to be aware of weak points in a beam to ensure they can hold the maximum possible weight
The bending moment M at a point in a beam is given by the formula below
M = _______
Where x metres is the distance from the point of support. Calculate the value of x when the bending moment is Nm. A trial and error method will not be accepted.
Re: Qudratic equation for bending point
If the bending moment is then we have:
Multiply through by 2, then distribute on the right:
Arrange quadratic in standard form:
Now, apply the quadratic formula to find x.
