Ahydraulic cylinder is to compress a car body down to bale size in 30 sec. the operation requires a 25 ft stroke and a 9500-lb force. if a 3000 psi pump has been selected and assuming the cylinder is 98% efficient find:

a) the required piston area in ft^2.

b)the required piston area in m^2.

c)the necessary pump flow rate.

d)the hydraulic horsepower delivered to the cylinder.

e)the output horsepower delivered by the cylinder to the load.

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

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
