Just didn't want to get bumped off. :-)

Homework Statement A heavy rope 3 m long is attached to the ceiling and allowed to hang freely. Let y = 0 denote the bottom end of the rope. To get started on this problem, imagine cutting the rope at an arbitrary value of y. Draw a free body diagram of each of the two pieces of rope to...

I am equally confused :). But thanks a lot for the help on the first part! If you treat the torque arm to be the full length of the stick, you get 3/2mgsin(theta) to be the torque. The only thing that comes close to equaling 1/4mgsin(theta) is if you treat the initial angle as not part of the...

Radial force of a rotating stick! 1. The Problem In this problem we want to learn a little bit about what is sometimes called dynamical loading. Our simple system consists of a uniform stick of length L and mass M hinged at one end. We would like to calculate the forces on the (frictionless)...

Homework Statement Consider a block of mass M that is pulled up an incline by a force T that is parallel to the surface of the incline. The block starts from rest and is pulled a distance x by the force T. The incline, which is frictionless, makes an angle theta with respect to the...

Just didn't want to get bumped to page 2. :-)

Homework Statement Consider the Atwood's machine of Lecture 8. We wish to use this machine to measure our local acceleration of gravity with an accuracy of 5% [i.e. (Delta g)/g = 0.05]. To begin, suppose we let the mass m_1 fall through a distance L. 3.1 Find an expression for the...

Yes, that fixed everything for me. I had thought that my professor wanted me to integrate both sides and leave the constants separate, but it was just coincidental that they were defined as c1 and c2. Thanks a lot!

Nothing...? :-(. I probably should have posted this earlier than the day before it's due.

Circular Motion Without Gravity- Calc Based URGENT! Homework Statement Consider a bead of mass m that is free to move around a horizontal, circular ring of wire (the wire passes through a hole in the bead). You may neglect gravity in this problem (assume the experiment is being done in...
