Question

During recess, Maria, who has mass 27.0 kg, hangs motionless on the monkey bars, with both hands gripping a horizontal bar. Assume her arms are vertical and evenly support her body. What is the tension in each of her arms?

Answer 1

@Michele_Laino please help :)

i suppose the acceleration should be g=9.81m/s^2

so then
F = m x a
i.e
T =m x a

n then in each arm the tension would be T/2

Answer 2

is it correct?
i would go for this

Answer 3

yes! correct! The tension \(T\) supported by each arm is: \(T=mg/2=...?\)

Answer 4

we can justify such conclusion by arguments of symmetry, of course
