Four bodies A, B, C, and D (which can be treated as particles) are attached to a shaft as shown in the figure. The masses of the bodies are 0.2, 0.4, 0.6, and 0.8 slug, respectively, and the distances from the axis of the shaft to their mass centers are 1.50 2.50, 2.00, and 1.25 ft, respectively. Find the mass center for the four bodies. ID 60 45 45 25 20 30 Froet View End View x in ft = ?

The net force exerted on a particle acts in the positive æ direction. Its magnitude increases linearly from zero at x = 0, to 500 Ñ at x = 2.8 m. It remains constant at 500 N from a 2.8 m to a = 8.0 m, and then decreases linearly to zero at x = 13.1 m Part A Determine the work done to move the particle from x = 0 to x = 13.1 m graphically, by determining the area under the F, versus graph.
