Three masses are connected by rigid massless rods, as shown. The 200-g mass (B) is located at the origin (0, 0). (a) Find the x- and y-coordinates of the center of mass. (b) Find the moment of inertia of this system of three connected masses when rotated about the r-axis that passes through mass B? (c) If this system is rotated about the r-axis, from rest to an angular speed of 6 rad/s in time t = 3 s, what...

Part E should say gear C not gear B
A gear reduction system consists of three gears A, B, and C. Gear A start from rest at time t = 0 and rotates clockwise with constant angular acceleration. Knowing that the angular velocity of gear A is 600 rpm at time t = 2s, determine (a) the anglular accelerations of gears B and C, (b) the accelerations of the points on gear B and C which are in contact when...
