Question

As the initially empty urinary bladder fills with urine and expands, its internal pressure increases by 3900 Pa, which triggers the micturition reflex (the feeling of the need to urinate). The figure shows a horizontal, square section of the bladder wall with an edge length of 0.0071 m. Because the bladder is stretched, four tension forces of equal magnitude T act on the square section, one at each edge, and each force is directed at an angle ? below the horizontal. What is the magnitude T of the tension force acting on one edge of the section when the uinternal bladder pressure is 3900 Pa and each of the four tension forces is directed 5.5

Explanation / Answer

P = 4Tcos?/A T = AP / 4cos? = (0.0071m)²(3900Pa) / 4cos5.5° T = 0.068N
