Unformatted text preview: Solution: The moment of inertia of a rectangular shape such as this one is easily calculated by using the equation I = 1/12 bh 3 . However, it is crucial that b and h are assigned correct values. Correct solutions should look like this: I xx = 1/12(10in)(15in) 3 = 2,812.5 in 4- (30 points) I yy = 1/12(15in)(10in) 3 = 1,250 in 4 - (30 points)...
