Dear Prof Scott

Is it possible to design and Construct a Pendulum clock where the pendulum can rotate 180 degree?.

Thanks

Prashant

No, for the pendulum swings slightly less every time. I mean, it may start out trying to do 180° by being straight out on one side, but it will quickly lose that potential that when it swings to the other side. I think the swing rate is determined by a multiple of cos(x) where x is the angle the pendulum swings from straight up and down. As x approaches 90°, the cos(x) approaches 0. As x stays near 0°, the cos(x) stays very close to 1. As can be seen in calculus, if f(x) = cos(x), f'(x) = -sin(x). With x near 0, -sin(x) is even closer to 0, so the cos(x) curve is almost level at this point.

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.

I have known about number theory since the mid 80's. I have answered over 250 questions on Number Theory with this software. Altogether, I have answered over 8,500 questions in mathematics.**Publications**

I have assisted many students in mathematics at OSU.
Perhaps I have assisted one of you're friends in math on a computer somewhere else,
but you don't even know... That would be late last night, perhaps with thousands of miles between us ...
Then again, if you're in Washington, so am I ...
