Unformatted text preview: ball, the greater force is required to change the ball's momentum, the larger tension in the strings is required. If the required tension force is larger than the maximum force that the strings can withstand, they break. P58*. P60. Figure 12-79 shows a simple truss that carries a load at the center (C) of ! 1.25 \$ N. Calculate the force on each strut at the pins, A, B, C, D, and determine which struts (ignore their masses) are under tension and which under compression.
