The four-bar mechanism lies in a vertical plane and is controlled by crank OA which rotates counterclockwise at a steady rate of 55 rev/min. Determine the torque M which must be applied to the crank at O when the crank angle θ = 41°. The uniform coupler AB has a mass of 9.6 kg, and the masses of crank OA and the output arm BC may be neglected.

The crank OA rotates in the vertical plane with a constant clockwise angular velocity
The crank OA rotates in the vertical plane with a constant clockwise angular velocity ωo=4.5 rad/s. For the position when OA is horizontal, (a) determine the angular acceleration of the uniform 10 kg slender bar AB and the horizontal and vertical components of the acceleration of its center of mass. Use the methods of kinematics (Ch 16) to establish both the magnitude and direction → or ← for aG and; CW or CCW for αAB) of each variable. (b) Draw complete free body...

Figure 8 (c) Figure 9 illustrates a four-bar linkage mechanism that is used to operate a washing system on a vegetable harvesting line. The mechanism consists of a crank OA which moves in a limited arc and an L-shaped connecting rod AB which tilts a large bucket of water DB onto the vegetables. The crank rotates with a constant angular velocity wOA = 4x rad/s. For the instant shown with the crank vertical and the angle 8 = 30° determine...
