Hello, can anyone explain to me what the moment of inertia is? we learned the mass moment, second moment and the first, and I'm getting confused as to what they all are. and can anyone explain what the strong/weak axis is? is it resistance to bending or rotation? i just can't visualize where the strong/weak axis would be on a ruler and our prof drew x and y axes but they don't make sense to me unless...you tilt the ruler?
he drew something like with the width of the ruler (not thickness) along the y axis.
