Answer:
a)
b))
c)
d)Power = 14.14 hp
e)Power =13.85 hp
Explanation:
Given that
t =30 s
S= 25 ft
F= 9500 lb
P= 3000 psi
1 psi = 6894.68 Pa
psi = pound force per inch square
a)
We know that
F = P A
9500 = 3000 A
We know that
1 inch = 0.0833 ft
b)
C)
Flow rate Q
d)
Power = P Q
Power = 10.55 KW
1 KW = 1.3 hp
Power = 14.14 hp
e)
Horsepower delivered by the cylinder to the load.= 0.98 x 14.14 =13.85 hp
Answer:
Explanation:
I can tell you what the answers for the middle column are, but if you don't know how to solve total energy problems, they won't make any sense to you at all.
First row, KE = 0
Second row, KE = 220500 J
Third row, KE = 183750 J
Fourth row, KE = 205800 J
That's also not paying any attention to significant digits because your velocity only had 1 and that's not enough to do the problem justice. I left all the digits in the answer. Round how your teacher tells you to.
Answer:
The horizontal force acting on m2 is F + 9.8m1
Explanation:
Given;
Block m1 on left of block m2
Make a sketch of this problem;
F →→→→→→→→→→→-------m1--------m2
Apply Newton's second law of motion;
F = ma
where;
m is the total mass of the body
a is the acceleration of the body
The horizontal force acting on block m2 is the force applied to block m1 and force due to weight of block m1
F₂ = F + W1
F₂ = F + m1g
F₂ = F + 9.8m1
Therefore, the horizontal force acting on m2 is F + 9.8m1
Answer:32 m/s/s
Explanation: since F=M*A, F=16N, M=0.5kg, A= F/M
A=16/0.5
A=32 m/s/s
Answer:
38.8 km/hr
Explanation:
The total distance is 2 × 282 km = 564 km.
The total time is 6 hr 32 min + 8 hr = 14 hr 32 min = 14.533 hr.
The average speed is:
(564 km) / (14.533 hr)
38.8 km/hr
