Answer:
The correct answer is letter "C": Both.
Explanation:
Industrial seals are used at interfaces between components to prevent leakage, to maintain heat, and to avoid contamination. The design, construction, and materials they use vary depending on industrial use but the most common are Polytetrafluoroethylene (PTFE), Nitrile Buna Rubber (NBR), and fluorocarbon.
Thus, using a sharp chisel could pry a seal out of a hole and a regular socket can often be used to force smaller metal-backed seals into place. Thus, technicians "A" and "B" are correct.

4-6. A vertical cylindrical storage vessel is 10 m high and 2 m in diameter. The vessel contains liquid cyclohexane currently at a liquid level of 8 m. The vessel is vented to the atmosphere. A 1-cm-diameter hole develops in the bottom of the vessel. Calculate and plot the discharge rate of cyclohexane as a function of time until the vessel is completely empty. Show that the time to empty is the same as the time calculated using Equation 4-21.

Answer:
E=1.969 × 10¹¹ Pa
Explanation:
The formula to apply is;
E=F*L/A*ΔL
where
E=Young modulus of elasticity
F=Force in newtons
L=Original length in meters,m
A=area in square meters m²
ΔL= Change in length in meters,m
Given
F= 8000 lb = 8000*4.448 =35584 N
L= 5 in = 0.127 m
A= 0.7 in² =0.0004516 m²
ΔL = 0.002 in = 5.08e-5 m
Applying the formula
E=(35584 * 0.127)/(0.0004516*5.08e-5 )
E=1.969 × 10¹¹ Pa
