bending point of a bean
can some help with this

the bending point in a beam is given in the formule below

M = 3x(20-x)
-----------
2

Where x meteres is the distance from the point of support. Calculate the value of x when the bending point is 40 Nm. A trial and error method will not be accepted

Also CAn you help me rearrange the below equation

I assume M = 40 ... multiply both sides by 2 and solve the resulting quadratic equation

Also CAn you help me rearrange the below equation

start by squaring both sides of the equation to remove the radical ...
