What is the formula for calculating the maximum load for a cantilever beam?
For a cantilever of length L, the moment at the support of a cantilever beam due to a uniform load ‘w’ (kg/m) is given as
M1 = (1/2) * w *(L)2
The moment at the support due to a point load P (kg) at the end is given as
M2 = P * L
The formula for the maximum stress a cantilever beam can tolerate is given by
σmax = (Mmax ) * (y) / (I), Where Mmax is the maximum moment (which is equal to M1 + M2), y is the distance from the center to the outer edge, and I is the area of the cross-section of the beam
