Answer:
theoretical fracture strength = 16919.98 MPa
Explanation:
given data
Length (L) = 0.28 mm = 0.28 × 10⁻³ m
radius of curvature (r) = 0.002 mm = 0.002 × 10⁻³ m
Stress (s₀) = 1430 MPa = 1430 × 10⁶ Pa
solution
we get here theoretical fracture strength s that is express as
theoretical fracture strength = 
.............................1
put here value and we get
theoretical fracture strength = 
theoretical fracture strength = 
theoretical fracture strength = 16919.98 MPa
Answer:

Answer:
The total rate of entropy generation is 6.665 W/K
Explanation:
Power input = current × voltage = 9.7 × 110 = 1067 W
Power output = 1.25 hp = 1.25 × 746 = 932.5 W
Total power = 1067 + 932.5 = 1999.5 W
Total rate of entropy generation = total power ÷ temperature of the surrounding = 1999.5 W ÷ 300 K = 6.665 W/K
