Use a lab balance to weigh the cart, the card, the string and all the masses. The pulleys are kept as light as possible so that their moment of inertia is low meaning that it can be ignored in any dynamical situation. Using these two equations, we can predict the frequency of any harmonics by measuring F, µ, and L. Place the string in the groove of the pulley. Pulleys are found on sailboats, on the end of cranes and even in the weight room of a workout gym. A pulley or pulley system will only lift a load if the input force is large enough to move the weight of each load. Predict the tension that the scale will read and record it on the chart.

Lab 7 - Rotational Motion Purpose: This Lab is intended as an introduction to the concepts of rotational inertia, rotational energy, and angular momentum. Although the data from this lab was inconclusive, it took more time for objects with more mass and friction (applied velcro/felt material) to reach the ground with the pulley system. This machine changes the direction of an applied force, allowing a heavy load to be moved. Adding the forces on each mass gives us the following picture: We can then solve for (the magnitude of) \(T\) 1 and \(a_y\) (operating under an assumption that \(m_1>m_2\)):. UTC Physics 1030L: Friction, Work, and the Inclined Plane 41 Since m1and m2 are connected by ropes, then the vertical distance S that m2 moves downward is the same distance along the path of the inclined plane that m1 moves. Hypothesis: I think with the weight and the different number of pulley systems being added each time the weight will be easier to lift every time we add a weight. The string must come off the large groove of the step pulley at 90º and be perfectly aligned to. AP Physics Lab The Atwood Machine. In spite of its importance, friction is still not well understood. Add an Ultra Pulley to your Photogate to monitor motion as a string passes over the pulley, or as the pulley rolls along a table. The pulley has a natural tendency to rotate with constant angular velocity, which must be overcome in order to accelerate the pulley. The tension after the pulley (T 1) and the mass added to the free end of the string were recorded and collected in a table, which can be found in Appendix A. Use your own hands and simple drawing tools to design, construct and explore the world of physics. , its mass is negligible compared to that of the block) and inextensible ( i.
