Answer:
1/2
Explanation:
Lets take N is the speed of engine in RPM.
As we know that in two stroke engine ,crank rotates one times in two stroke of piston.Every rotation of crank gives one power stroke.It means that two stroke give one power stroke.
On the other hand in four stroke engine,crank rotates two times in 4 stroke of piston.It means that 4 stroke of piston gives one power stoke .
So we can say that the ratio of number of power stroke in two stroke engine to the number of power stroke in four stroke engine is 1/2.
That is too hard but u got that cuz i believe in you!!!
Answer:
The appropriate solution is "1481.76 N".
Explanation:
According to the question,
Mass,
m = 540 kg
Coefficient of static friction,
= 0.28
Now,
The applied force will be:
⇒
By substituting the values, we get
Answer:
C. 14.55
Explanation:
12 x 10 = 120
120 divded by 10 is 12
so now we do the left side
7 x 3 = 21 divded by 10 is 2
so now we have 14
and the remaning area is 0.55
so 14.55
