Mass of man is = 80KG Mass of the ladder is = 20 KG Mass of the bar connecting the two halves of the ladder is negligible. The friction force between floor and ladders are negligible. (floor is frictionless) Question: find the tension in the horizontal bar connecting the two halves of the ladder... Here is the figure: I am wondering if it is possible to calculate the tension, without knowing the dimensions of the ladder??It is not right?
