Question

Three thin rods, each of length $L$, are arranged in an inverted $U$, as shown in Fig. 8- 16. The two rods on the arms of the $U$ each have mass $M$; the third rod has mass $3 M$. Where is the center of mass of the assembly?

Step 1

Step 1: Calculate the x-coordinate of the center of mass using the formula: \[ X_{\text{cm}} = \frac{\sum m_i x_i}{\sum m_i} \] where $ m_i $ is the mass of each rod and $ x_i $ is the x-coordinate of each rod. Show more…
