Answer:
The diameter of the shaft is 80.5 mm.
Explanation:
Torsion equation is applied for the diameter of the solid shaft.
Step1
Given:
Power of the shaft is 100 kw.
Revolution per minute is 160 RPM.
Allowable shear stress is 70 Mpa.
Maximum torque is 20% more than the mean torque.
Step2
Mean torque is calculated as follows:
T=5968.31 N-m
Step3
Maximum torque is calculated as follows:
T_{max}=7161.97 N-m
Step4
Apply torsional equation for diameter of shaft as follows:
d=0.0805 m
or,
d=80.5 mm
Thus, the diameter of the shaft is 80.5 mm.
A distillation column is an essential item used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on the differences in volatilities. Fractionating columns are used in small scale laboratory distillations as well as large scale industrial distillations.

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.
