Question

A uniform bar, OA, of mass 13.2 kg is held in equilibrium by the cable AB. The lengths a and b are 1.5 and 1.1 m respectively. Determine the tension in the cable AB.

Answer 1

The question involves the calculation of tension in a cable supporting a bar in equilibrium, requiring additional information such as angles or other forces to solve.

Step-by-step explanation:

The student is asking about finding the tension in the cable that holds a uniform bar in equilibrium. As per the problem statement, we know the mass of the bar (13.2 kg) and the lengths a (1.5 m) and b (1.1 m). However, to determine the tension in the cable AB, we need more information, such as the angle at which the cable is attached to the bar or the wall, or additional forces acting on the system. Without this information, it's not possible to calculate the tension. In general, the problem involves creating a free-body diagram, identifying all forces, and applying equilibrium conditions: sum of the forces in any direction and sum of moments about any point must be equal to zero.
