Ok I was given this problem:
Problem: The deflection d of a cantilever beam of length L is given by the mechanics of materials equation [tex]d=PL^3/3EI[/tex]Where P is the force on the end of the beam and E is the modulus of elasticity, which has the same dimensions as pressure.Determine the dimensions of I which is the moment of Inertia.
Are they simply asking you to manipulate the equation for I? If so would the following be correct? A little help would be appreciated, thanks.
[tex] I= 1/d(PL^3/3E)[/tex]
