Question

A uniform beam has a length 8 m and mass 60 kg. If it is suspended by two ropes as shown below, find the tension T. (Ropes at 1 m and 2 m from ends?)
Options
A 588 N
Correct Answer
B 353 N
C 441 N
D 784 N
Correct Answer

Option A is the correct answer.

Detailed Explanation

Weight = 60×9.8 = 588 N. If symmetrical, each rope might share equally, so 294 N each. But options have 588 N, which is total weight. Possibly T is the tension in one rope, and the other rope has different tension. Without diagram, cannot determine.

Hint

Use equilibrium conditions.
