Answer:
17330204.91 Pa
Step-by-step explanation:
Stress is defined as force applied per unit area and it is calculated in Pa.
Formula to calculate stress is
Stress = Force / Area
1)
Force = mg + ma
(acceleration of the mass is zero because it is stationary)
= 50(9.8) + 50(0)
= 490 N
2)
Area = πr²
(1m = 1000mm
1mm=1/1000)
= π (3*10^-3)²
3)
stress = Force / Area
= 490 / π(3*10^-3)²
= 17330204.91 Pa
