Question

(c) The area of cross section of press plunger of a hydraulic press is 4m. It is
required to overcome a resistive load of 400kgf on it. Calculate the force
required on the pump plunger if the area of cross section of the pump plunger
is 0.01m2.(4)​

Answer 1

Answer:

The area of cross section of press plunger of a hydraulic press is 4m2 4m . It is required to overcome resistive load of 400kgf on it. Calculate the force required on the pump plunger if the area cross section of plunger is 0.01m2. manishvermadwl123 is waiting for your help.

Answer 2

Answer:

Load=900kgf,Effort(E)=?

Area of cross section of the press plunger =a

1

=9m

2

Area of cross - section of the pump plunger =a

2

=0.03m

2

By Pascal's law,

Pressure exerted by pump plunger = pressure exerted on press plunger.

i.e.,

E

L

=

a

a

1

⇒

E

900kgf

=

0.03m

2

9m

2

⇒E=

9m

2

900kgf×0.03m

2

=3kgf.
