Un peso de 80 kg está suspendido de un cable cuyo diámetro es de 0.01 m. ¿Cuál es el esfuerzo en el cable?

the answer for apex is the lowest

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
