Answer:
The percentage ductility is 35.5%.
Explanation:
Ductility is the ability of being deform under applied load. Ductility can measure by percentage elongation and percentage reduction in area. Here, percentage reduction in area method is taken to measure the ductility.
Step1
Given:
Diameter of shaft is 10.2 mm.
Final area of the shaft is 52.7 mm².
Calculation:
Step2
Initial area is calculated as follows:


A = 81.713 mm².
Step3
Percentage ductility is calculated as follows:


D = 35.5%.
Thus, the percentage ductility is 35.5%.

Answer:
reservoir is 727°C, then low temperature
Explanation:
Efficiency for any Heat engine = Work done by engine / Heat provided to the engine
Also, for a carnot engine derived formula for Carnot Engine
= 1- T2/T1
Where, T2 = sink reservoir temperature
and T1 = source reservoir temperature
727° C = 1000 K
So, 0.75 = 1-T2 / 1000
So, T2 = 1000*0.25 = 250 K = -23 Kelvin
Answer: Roundworm, hookworms, whipworms.
Explanation: Ascarids can be defined as any leaf insect or walking stick insect; phasmid nematode of the family Ascarididae.
They cause the disease ascariasis in humans and mammals and examples of them are roundworm, hookworm and whipworm.
