Two uniform bars of the same dimensions are constructed from the same material. One bar has five evenly spaced holes through it and the second bar has only two holes. In these cases, the bars are slid over vertical pegs and rest on a horizontal surface, where friction between the bar and the surface is negligible. The two bars are each pulled by horizontal forces of equal magnitude F from their right end as shown above. The bars’ resulting angular accelerations are recorded.
Is the magnitude of the initial angular acceleration of the bar in Case 1 larger than, smaller than, or equal to the magnitude of the initial angular acceleration of the bar in Case 2? Explain your reasoning.
