A bra can handle a tension force for about 150 newton. Assume the.. rounded thing have a weight of 6g, and the milk tea is around 0.5g, where g is referred to the acceleration due to graphic. Based on rough calculation, it will give a total weight of 63.765N.
However, due to the fact that the the tension force of the bra is not vertical,so, the actual reaction force produced is much higher than 63.765N to support the weight.
By simplified into above diagram, we can calculate the reaction force by this formula:
R=W/sin(angle of attack)
If we assume the angle of attack is about 22.5 degree, the reaction force is about 166.63 Newton. If the reaction force it needed to produce is higher than the maximum tension a bra can handle, following scenario can be produced:
A. The angle of attack is increased, thus, the milk tea is falls from the rounded object
B. the bra was torn off
C. The angle of attack is increased, but, the fiction provided between the rounded object and milk tea can still hold it.
Still, the calculation is very rough, as above assume that the body does not provide force to support the rounded object, and the contact between milk tea and rounded object is horizontal, which reduce the fiction provided to the milk tea, etc.
In closing, no conclusion is given, and this wastes 20 minutes of my time.
