Position a pole across the back of a chair (serving as a fulcrum) and hang a two­ pound weight on one end of the pole. Position a five ­pound weight on the other side of the pole such that the weights are balanced. Measure and record the distances of the two weights from the fulcrum and write an explanation of your results.

Finding the Spring Constant We can describe an oscillating mass in terms of its position, velocity, and acceleration as a function of time. We can also describe the system from an energy perspective. In this experiment, you will measure the position and velocity as a function of time for an oscillating mass and spring system, and from those data, plot the kinetic and potential energies of the system. Energy is present in three forms for the mass and spring system....

Background: Part I: Converging Lenses First, grab the lamp, and place it at one end of the optical track. Ensure that the light is directed to shine on the rest of the track (without anything in the way of the "window" on the lamp). Then, select a 5cm converging lens (red tape), and place it in a holster in the middle optical track. Place the arrow in a clip stand, and place that clip stand in a holster in between...

Question: If we had put the arrow and the lamp really far away in Part I, what would be the distance between the (5cm converging) lens and the image? What would the magnification be? What would the orientation be? (Hint: there's both a mathematical and physical way to understand this.) Part I: Converging Lenses First, grab the lamp, and place it at one end of the optical track. Ensure that the light is directed to shine on the rest of...

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...

Targeting Specific Muscles 1. Review the descriptions of different bodybuilding exercises below .2. Try doing or simulating each exercise with your own body (without the weights of course). 3. Based on the descriptions of which actions are performed by each muscle, and information about where the muscles insert into bones, try to determine which muscle is targeted by the exercise. Note that each exercise targets one of the muscles in the list below. 4. In your notebook record:. The name...

Two painters are working on a platform hanging off the side of a building. The platform is 10 meters long and supported by two cables. The painters are represented by vector forces in the free-body drawing below. The weights of the objects are: Platform 184 N, Sue 130 N, Jack 220 N. Calculate the force in each cable when the painters are in the position shown below(Case 1). To start, locate the pivot point where Cable 1 attached to the...

MOMENT OF INERTIA LAB Apparatus Only (P3) With Masses (P4) With Block (P5) Setup You have a T-shaped apparatus that can spin about a vertical axis. One end of a light string is wrapped around the vertical shaft of the apparatus. The other end passes over a pulley and has a known mass hung from it to establish tension in the string. By measuring the acceleration of the hanging mass, the rotational inertia of the apparatus can be determined. Specifically,...
