Question

A heavy block is supported by three lines as shown.Which of the following statements is true in its entirety? A)T₁ > T₂ and T₂ > T₃ B)T₂ > T₁ and T₁ > T₃ C)T₂ > T₃ and T₃ > T₁ D)T₃ > T₁ and T₁ > T₂ E)T₁ > T₃ and T₂ > T₃

Quizplus · Accepted Answer

The block is in equilibrium, so the forces acting upward must equal the force acting downward. T₂ is the largest upward force, so it must be greater than the two other upward forces T₁ and T₃. Therefore, T₂ > T₃ and T₃ > T₁. Choice C satisfies both of these conditions.
