Answer:
Nikolaus Otto invented the first atmospheric gas engine.
George Brayton invented the first combustion engine.
Answer:
Explanation:
Compression ratio:
Compression ratio is the ratio of volume in the cylinder.Generally it is denoted by r.
The compression ratio for Otto cycle is about 8 to 12.But the compression ratio of diesel engine is about 14 to 25.
So from the Otto cycle compression ratio can be define as
As we know that efficiency defines as the ratio of work out to the heat input.In the Otto cycle the efficiency is given as in terms of compression ratio r as
Where γ is the heat capacity ratio.
Answer with Explanation:
The general equation of simple harmonic motion is
where,
A is the amplitude of motion
is the angular frequency of the motion
is known as initial phase
part 1)
Now by definition of velocity we have
part 2)
Now by definition of acceleration we have
part 3)
The angular frequency is related to Time period 'T' as
where
is the angular frequency of the motion of the particle.
Part 4) The acceleration and velocities are plotted below
since the maximum value that the sin(x) and cos(x) can achieve in their respective domains equals 1 thus the maximum value of acceleration and velocity is and respectively.
