tes about a fixed axis, what is true about all the points in the object? ... They all have the same radial acceleration. 2) The figure shows scale drawings of four objects, each of the same mass and uniform thickness, with the mass distributed uniformly. Which one has the greatest moment of inertia when rotated about an axis perpendicular to. Test 3 Problem 2. This is problem 11-39, one of the suggested extra problems. It should be clear that this is [at least until part c)], a typical statics problem. a) We draw a force diagram for the beam, with coordinate system x=horizontal and y=vertical, as shown. The only forces acting on it are the tension T, the weight Mg, and the force.
