Yo-yo pulled to stay in place

[QUOTE="haruspex, post: 5503755, member: 334404"] You quote the MoI for a ball, but yoyos are normally more cylindrical, in my experience. You can simplify the expression for T[SUB]d[/SUB]. Have another think about T[SUB]u[/SUB]. You've used ##\dot y## for linear acceleration. You mean ##\ddot y##, I guess. In the final line, the dot seems to have slipped off the y. Otherwise, all looks good. [/QUOTE]
