Question

Figure 5.6 3) 3) A 6.0 kg box is held at rest by two ropes that form 30° angles with the vertical. An external force Facts vertically downward on the box. The force exerted by each of the two ropes is denoted by T. A force diagram, showing the four forces that act on the box in equilibrium, is shown in Figure 5.6. The magnitude of force F is 410 N. The magnitude of force T is closest to: STATIC EQUILIBRIUM PROBLEM A) 271 N B) 376 N C) 235 N D) 470 N E) 188 N Figure 5.7

Answer 1

In equilibritem Tsin30 {fy=0 T Tcos 30 2T Cos30° = WIF => T = WHE 2 C0330 6x9.8+410 - 270.66 N. 2 * 13/2 so T~ 27IN A is correct
