Answer:
speed = 16.44 m/s
Acceleration = 71.36 m/s²
Explanation:
Given data
Speed ( N) = 240 rpm
angle = 45°
stoke length(L) = 750 mm
length of rod ( l ) = 1500 mm
To find out
the piston speed and acceleration
Solution
we find speed by this formula
speed = r ω (sin(θ) + (sin2(θ)/ 2n)) ...................1
here we have find r and ω
ω = 2
N / 60
so ω = 2 × 240 / 60
ω = 25.132 rad/s
n = l/r = 1500/750 = 2
we know L = 2r
so r = L/2 = 750/2 = 375 mm
put these value in equation 1
speed = 375 × 25.132 (sin(45) + (sin2(45)/ 2×2))
speed = 16444.811823 mm/s = 16.44 m/s
Acceleration = r ω² (cos(θ) + (cos2(θ)/ n)) ...................2
put the value r, ω and n in equation 2
Acceleration = r ω² (cos(θ) + (cos2(θ)/ n))
Acceleration = 375 × (25.132)² (cos(45) + (cos2(45)/2))
Acceleration = 71361.363659 = 71.36 m/sec²

I was about to click it on a question I saw.
Engineering ethics is not without abstraction, but in contrast with computing, it is animated by a robust and active movement concerned with the seamless identification of ethics with practice.
<h3 /><h3>What is engineering?</h3>
This is a branch of science and technology concerned with the design, building, and use of engines, machines, and structures that uses scientific principles.
Comparing ethics in engineering and ethics in computing:
- Engineering ethics are a set of rules and guidelines. While computing ethics deals with procedures, values and practices.
- In engineering ethics, engineers must adhere to these rules as a moral obligation to their profession While in computing ethics, the ethics govern the process of consuming computer technology.
- Following these ethics for the two professions will NOT cause damage, but disobeying them causes damage.
Some practical examples in the computing field:
- Avoid using the computer to harm other people such as creating a bomb or destroying other people's work.
- Users also should not use a computer for stealing activities like breaking into a bank or company.
- Make sure a copy of the software had been paid for by the users before it is used.
Some practical examples in the engineering field:
- Integrity for oneself.
- Respect for one another.
- Pursuit of excellence and accountability.
Hence, Engineering ethics is the field of system of moral principles that apply to the practice of engineering and following them is important to the profession.

Answer:
189.15cy
Explanation:
To understand this problem we need to understand as well the form.
It is clear that there is four wall, two short and two long.
The two long are 
The two long are 
The two shors are 
The height and the thickness are 14ft and 0.83ft respectively.
So we only calculate the Quantity of concrete,
![Q_c = [(2*122.08)+(2*86-375)]*14*0.833\\Q_c=4864.02ft^3](https://tex.z-dn.net/?f=Q_c%20%3D%20%5B%282%2A122.08%29%2B%282%2A86-375%29%5D%2A14%2A0.833%5C%5CQ_c%3D4864.02ft%5E3)
That in cubic yards is equal to 
Hence, we need order 5% plus that represent with the quantity
