    Physical Pendulum Question (Mass on a Grandfather Clock)

    Ahh this makes sense and is very clear, thank you. In the calculation I just did I used d just as the distance from the mass to the pivot point and got the right answer. Thank you so much for your help!

    Physical Pendulum Question (Mass on a Grandfather Clock)

    What I'm thinking is that d is the distance from the center of mass, but the pivot point is the end of the rod. I guess I'm just confused, would you be able to rephrase the question please? Thank you for your help.

    Physical Pendulum Question (Mass on a Grandfather Clock)

    Ahh, that makes sense, the moment of intertia for the weight is not mL^2 since it's not at the end of the rod, it should be m(d+L/2)^2 right? So the inertia should be I = (1/3)ML^2 + m(d+L/2)^2 [I think] Except I solved for d using d = Iπ^2/((M+m)g) and substituting the I from above and got the...

    Physical Pendulum Question (Mass on a Grandfather Clock)

    Homework Statement You are at a furniture store and notice that a grandfather clock has its time regulated by a physical pendulum that consists of a rod with a movable weight on it. When the weight is moved downward, the pendulum slows donw; when it is moved upward, the pendulum swings faster...

    Calculating the Force on a Bicycle Wheel

    I have been trying this problem for a while and can't seem to figure it out: A bicycle wheel has a radius R = 32.0 cm and a mass M = 1.82 kg which you may assume to be concentrated on the outside radius. A resistive force f = 137 N (due to the ground) is applied to the rim of the tire. A force...
