SUMMARY
The discussion centers on solving a torque and static equilibrium problem involving a uniform plank supported by three ropes. The plank measures 2.00m in length and has a mass of 30.0 kg, with a 700N person positioned 5m from the left end. The participant successfully calculated the tension in the first rope (T1) as 501N and the second rope (T2) as 672N, while determining that the third rope (T3) exerts a force of 384N. The participant utilized the equations for torque and static equilibrium, specifically ∑T = 0 and ∑F = 0, to arrive at these conclusions.
