Answer:
D. Inspecting the muffler
Explanation:
HVAC/refigeration systems are sealed systems that use refrigerant not combustion. A muffler is found on combustion systems.
You would disconnect, flush, seal, and possibly replace the condenser if the condenser is found to be failing.
Answer:
The correct answer is C. World Coordinate System
Explanation:
The World Coordinate System has to do with that coordinate system which is fixed in the activities of the CADing. There is a default system in which we can refer to them as soon as we want to manipulate the objects and add new elements.
Answer:
2.77mpa
Explanation:
compressive strength = 20 MPa. We are to find the estimated flexure strength
We calculate the estimated flexural strength R as
R = 0.62√fc
Where fc is the compressive strength and it is in Mpa
When we substitute 20 for gc
Flexure strength is
0.62x√20
= 0.62x4.472
= 2.77Mpa
The estimated flexure strength is therefore 2.77Mpa
Answer:
a) (option B) 230 kPa
b) (option A) 100 N/m
Explanation:
Given:
Diameter, d = 25 m
Thicknesses, t = 15 mm
Yield point = 240 MPa
Factor of safety = 2.5
a) To find the maximum internal pressure, let's use the formula:
Solving for P, we have:
P = 230.4 kPa
≈ 230 kPa
The maximum permissible internal pressure is nearly 230kPa
b) Given:
Thickness, t = 6.35 mm
L = 203 mm
Torque, T = 8 N m
Let's find the mean Area,
mA = (l - t)²
= (203 - 6.5)²
= 38671.22mm²
≈ 0.03867 m² (converted to meters)
To find the average shear flow, let's use the formula:
q = 103.4 N/m approximately 100N/m
The average shear force flow is most nearly 100 N/m
