1. For the mechanism shown in Figure 1, consider the position where the various coordinates are those given below the figure. The point C denotes the center of curvature of the slotted link at the position denoted by D. When the mechanism is in the position shown, the crank BD has an angular velocity and angular acceleration given by, ω ~ 2 = 16.370k̂ rad/sec, α ~ 2 = 4.030k̂ rad/sec2 . Determine the angular acceleration of link 3 at this position. 1 0 0 1 B 1 0 1 0 1 2 D 3 A C 11111111 00000000 00000000 11111111 Figure 1: Slider mechanism.

The gears have radii as follows: rR = 206.400mm, rS = 124.200mm and rP = 41.100mm. Taking counter-clockwise as positive, the two inputs to the system are ωR = 6.800rad/s and ωS = 14.700rad/s. Determine the angular velocity of the carrier OA. R P O A S Figure 2: Epicyclic gear train.
