There's only one torque in this problem and it's going to be the torque from the friction force. So that's going to equal . So remember this is just going to be friction times the distance times the sine of the angle equals, and this moment of inertia here.
Topics: On this worksheet you will practice using the basic formulas for torque and subsequent rotational behavior.
Write out an equation for the torque acting on the pulley/disk. Write out a third equation relating angular acceleration, and the acceleration of the hanging mass.
Investigate how torque causes an object to rotate. Discover the relationships between angular acceleration, moment of inertia, angular momentum and torque.
Net torque (N·m) 2. Use Excel to plot the torque along the vertical axis and the angular acceleration along the horizontal axis. Add a trendline and display its equation on the graph. Print the graph and staple to this worksheet before you turn it in. Slope of graph = Measured moment of inertia = kg·m2
calculate the rotational inertia of a system that includes one or more masses at different radii from the center of rotation. Language Objectives: Understand and correctly use the terms “rotational inertia” and “torque.” Accurately describe and apply the concepts described in this section using appropriate academic language.
We have three methods for calculating torque about a particular point. R θ Force acts here. F Force acts here. R Force acts here. Use this method if both R and θ are easy to find. Use this method if the lever arm is easy to find. Use if Rr and Fr are easy to break into components.
