E is in GPa , 1 Pa = 1 kg m^-1 s^-2
I is in m^4
m is in kg and L is in m.
But in the equation for the total I, there is the term of ma^2. Doesn't that have units kgm^2 or am i getting wrong somehow?
Hello! I have a problem and if anyone could help that would be great.
Imagine that you have a cantilever beam of length L and has an end mass m. In order to calculate the natural frequency I use the equation:
f=(1/2*pi)*SQRT(3EI/mL^3).
a) The moment of inertia in the equation is the sum...
