Answer:
B.29
Explanation:
In general purpose acme thread:
Nominal depth of thread=0.5
Included angle =29 degrees
Generally Acme thread are following types
1.General purpose(G) Acme
2.Centralizing(C) Acme
3. Stub Acme
Centralizing(C) Acme threads have tighter tolerance during manufacturing as compare to General purpose(G) Acme threads.

Answer:
The amount of cargo the plane can carry is 8707.89 N
Explanation:
The surface area of the wings facing the air = 30×6×2 × sin(2.5) = 15.7 m²
The speed of the plane 550 km/h = 152.78 m/s
The volume of air cut through per second = 15.7 × 152.78 = 2399.07 m³
The mass of air = Volume × Density = 2399.07 × 0.37 = 887.65 kg
Weight of air = Mass × Acceleration due to gravity = 887.65 × 9.81 = 8707.89 N
Given that the plane is already airborne, the additional cargo the plane can carry is given by the available lift force of the plane.
The amount of cargo the plane can carry = 8707.89 N
Answer:
Civil Engineering.
Explanation:
Civil Engineering is a field of engineering study that deals with professional practising in designing and developing infrastructures such as transport system and networks, buildings, etc.
<u>Civil engineering is regarded as the second--oldest form of engineering studies in the field of engineering.</u>
<u>A person who studies civil engineering is able to design and develop major projects in transportations system such as road construction, bridges, airports, tunnels, etc.</u>
So, Danny, who is interested in studying transporation networks and system should opt for studying civil engineering.
