Answer:
a) 93.852 kN
b) 128.043 mm
Explanation:
Stress is load over section:
σ = P / A
If plastic deformation begins with a stress of 297 MPa, the maximum load before plastic deformation will be:
P = σ * A
316 mm^2 = 3.16*10^-4
P = 297*10^6 * 3.16*10^-4 = 93852 N = 93.852 kN
The stiffness of the specimen is:
k = E * A / l
k = 113*10^9 * 3.16*10^-4 / 0.128 = 279 MN/m
Hooke's law:
x' = x0 * (1 + P/k)
x' = 0.128 * (1 + 93.852*10^3 / 279*10^6) = 0.128043 m = 128.043 mm
Answer:
Explanation:
given data:
maximum temperature = 727 degree C =727 +273 = 1000 K
Minimum temperature = 27 degree C = 27 +273 = 300 K
Maximum efficiency is given as 
plugging all value from the above to get maximum efficiency
Answer:
b) socialism
Explanation:
Conflict theory focuses on the competition between groups within society over limited resources. Conflict theory views social and economic institutions as tools of the struggle between groups or classes, used to maintain inequality and the dominance of the ruling class.
