You are asked to design the decorative mobile shown in ?Fig. P11.56?. The strings and rods have negligible weight, and the rods are to hang horizontally. (a) Draw a free-body diagram for each rod. (b) Find the weights of the balls A, B, and C. Find the tensions in the strings S1, S2, and S3. (c) What can you say about the horizontal location of the mobile’s center of gravity? Explain.
Solution 60P Step 1: Introduction : In this question, we need to draw the free body diagram for the rods In the second part we need to find the weight of balls and tension along the three strings In the third part we need to explain mobile’s center of gravity
