The radius of the specimen is 60 mm
<u>Explanation:</u>
Given-
Length, L = 60 mm
Elongated length, l = 10.8 mm
Load, F = 50,000 N
radius, r = ?
We are supposed to calculate the radius of a cylindrical brass specimen in order to produce an elongation of 10.8 mm when a load of 50,000 N is applied. It is necessary to compute the strain corresponding to this
elongation using Equation:
ε = Δl / l₀
ε = 10.8 / 60
ε = 0.18
We know,
σ = F / A
Where A = πr²
According to the stress-strain curve of brass alloy,
σ = 440 MPa
Thus,
Therefore, the radius of the specimen is 60 mm

No. If you just wanna write code you dont need that, but if you wanna be an Architect for designing robots or something then yeah
Answer:
efficiency of the engine is 0.4167
Explanation:
given data
T high = 1200 K
T low = 700 K
solution
we get here efficiency that is express as
efficiency = 
.........................1
put here value of both temperature we get efficiency
efficiency = 1 - 
efficiency = 1 - 0.58333
efficiency = 0.4167
so efficiency of the engine is 0.4167
