A steel cylindrical sample was subjected to a tensile test. The yield load was 2100N. The maximum load was 3400N and the failure

Misha Larkins [42]

Answer:

initial diameter of the sample is 2.95 mm

Explanation:

given data

yield load = 2100 N

maximum load = 3400 N

failure load = 2350 N

ultimate engineering stress = 497.4 MPa = 497 × $10^{6}$ N/m²

to find out

What was the initial diameter of the sample in mm

solution

we will apply here ultimate engineering stress formula that is express as

ultimate engineering stress = $\frac{Pmax}{A}$ ...............1

here A is area and P max is maximum load applied

so area = $\frac{\pi }{4} d^2$

here d is initial diameter

so put all value in equation 1

497 × $10^{6}$ = $\frac{3400}{\frac{\pi }{4} d^2}$

solve it we get d

d = 2.95 × $10^{-3}$ m

so initial diameter of the sample is 2.95 mm

Magnetic micro-generators are considered for the recovery of mechanical energy from vibrations. a)-True b)- False,

sleet_krkn [62]

Answer:

False

Explanation:

Magnetic micro generators are used to generate power making use of very small generators for generation of electricity and consists of prime movers, electric generators of quite small size or conversion devices in order to convert environmental energy like heat or vibrations into electrical energy and not mechanical energy.

Therefore, magnetic micro generators are not used for the recovery of mechanical energy from vibrations but electrical energy from them.
