Answer:
- Driving surface area as subject to differential pressures
- How to achieve continuous rotation
- Mechanical connections
Explanation:
The general stages of thinking when designing a system are;
- First understanding the problem that requires you to design a solution
- Defining the problem that needs to be solved. In this case is to design an efficient hydraulic engine for a motorboat
- Research to find any available solutions for similar problems
- Idea of the solution
- A prototype to try solve the challenge
- Selecting and adjusting the prototype as you implement the solution.
For a hydraulic engine design, the following designing parts are vital;
- Driving surface area as subject to differential pressures
- How to achieve continuous rotation
- Mechanical connection
Pressures are important due to motor displacements. Fuel burns in the cylinder to cause power through fuel gases burning and expansion which is the four-stroke cycle. Continuous rotation will come in the design considerations through reciprocating motions of pistons into rotary motions. Mechanical connections are vital especially in crank shaft turns, gear box that turns horizontal motions to spinning motions and finally the propeller that drives the boat on the water.
Answer: Due to the way that spur gears work, starters that use them require an offset armature, which is achieved by placing the starter drive in separate gear housing. In starters that use planetary gears, the gears can be contained in an in line drive-end housing.
Explanation: true
Answer:
correct option is (A) 0.5
Explanation:
given data
axial column load = 250 kN per meter
footing placed = 0.5 m
cohesion = 25 kPa
internal friction angle = 5°
solution
we know angle of internal friction is 5° that is near to 0°
so it means the soil is almost cohesive soil.
and for a pure cohesive soil
= 0
and we know formula for is
= (Nq - 1 ) × tan(Ф) ..................1
so here Ф is very less should be nearest to zero
and its value can be 0.5
so correct option is (A) 0.5
Answer:
Monopsony
Explanation:
Kinda like a monopoly, except instead of one producer it is one buyer.
the answer is C cause drivers dont always follow the rules
