Answer:
Poissons ratio = -0.3367
Explanation:
Poissons ratio = Lateral Strain / Longitudinal Strain
In this case, the longitudinal strain will be:
Strain (longitudinal) = Change in length / total length
Strain (longitudinal) = (8.40392 - 8.4) / 8.4
Strain (longitudinal) = 4.666 * 10^(-4)
While the lateral strain will be:
Strain (Lateral) = Change in length / total length
Strain (Lateral) = (2.09967 - 2.1) / 2.1
Strain (Lateral) = -1.571 * 10^(-4)
Solving the poisson equation at the top we get:
Poissons ratio = -1.571 / 4.666 <u>( 10^(-4) cancels out )</u>
Poissons ratio = -0.3367
Answer:
Employers must comply with OSHA's regulations to safeguard workers from caught-in or -between dangers, which include, but are not limited to, the following:
• Protect power tools and other equipment with moving parts with guards.
• Support, secure, or otherwise make safe any equipment that has pieces that workers could become entangled in.
· Take precautions to avoid workers being crushed by tipped-over heavy machinery.
• Take precautions to avoid pinning workers between equipment and a solid object.
• Provide workers with protection when trenching and excavating.
• Provide ways to prevent constructions, such as scaffolds, from collapsing.

Answer:
the compound light microscope
Explanation:
The stereomicroscope is to study section to study the entire objects in three dimensions at low magnification. A Compound light microscope is used for small or thinly sliced objects under higher magnification than stereomicroscope.
Answer:
the rate of heat loss from the steam turbine is Q = 200 kW
Explanation:
From the first law of thermodynamics applied to open systems
Q-W₀ = F*(ΔH + ΔK + ΔV)
where
Q= heat loss
W₀= power generated by the turbine
F= mass flow
ΔH = enthalpy change
ΔK = kinetic energy change
ΔV = potencial energy change
If we neglect the changes in potential and kinetic energy compared with the change in enthalpy , then
Q-W₀ = F*ΔH
Q = F*ΔH+ W₀
replacing values
Q = F*ΔH+ W₀ = 420 kg/min * (-600 kJ/kg) * 1 min/60 s * 1 MW/1000 kW + 4 MW = -0.2 MW = -200 kW (negative sign comes from outflow of energy)
