1 . A hydraulic lift office chair provides its couch attached to a piston with an area of 11. a couple of cm2. The chair can be raised by simply exerting pressure on another piston, with an area of 4. doze cm2. When a person seated on the seat exerts a downward pressure of 219 N, what force needs to be exerted for the small intervention to lift the seat?

Answer: a= 14. 2 cm2

A= 4. 12 cm2

f= 219 N

F= 80. 56 N

F= fA as well as a; (219 N) (4. 12 cm2 ) / 11. two cm2 = 80. 56 N

F/ f sama dengan 80. 56 N/ 219 N = 0. thirty seven

A/ a = 5. 12 cm2 / 14. 2 cm2 = zero. 37

installment payments on your In changing a tyre, a hydraulic jack elevates 7468 In on its large intervention, which has the of twenty-eight. 27 cm2. How much pressure must be exerted on the little piston if this has an area of 1 . 325 cm2?

Answer: a= 1 . 325 cm2

A= twenty-eight. 27 cm2

F= 7468 N

f= 350. 02 N

Remedy:

f= Fa / A; (746 N)(1. 325 cm2 ) as well as 28. 27 cm2 = 350. 02 N

F/ f= 7468 N / 350. 02 = 21. 34

A/ a= twenty eight. 27 cm2 / 1 ) 325 cm2 = twenty one. 34

three or more. An engine store uses a lift up to raise a 1784 N engine. The lift contains a large intervention with a location of seventy six. 32 cm2. To raise the lift, power is exerted on a small piston with an area of 12. 56 cm2. What force has to be exerted to boost the lift up?

Answer: F= 1784 In

A= 76. 32 cm2

a= doze. 56 cm2

f= 293. 59 N

Solution:

f= Fa / A; (1784 N)(12. 56 cm2 ) / 76. 32 cm2 = 293. 59 D

F/ f= 1784 D / 293. 54 In = 6. 08

A/ a= 76. 32 cm2 / doze. 56 cm2 = six. 08

3. In a newly designed car with a hydraulic braking system, a force of 85 In is put on one of the grasp cylinders, which includes an area of 8. you cm2. The master tube is linked to one braking system piston, which usually exerts a force of 296 N. What is the region of the brake pedal piston? Answer: f= 85 N

A= 8. 1 cm2

F= 296 In

A= 28. 21 cm2

Solution:

A= Fa/ farrenheit; (296 N)(8. 1 cm2 ) / 85 D = twenty-eight. 21 cm2

F/ f = 296 N as well as 85 And = a few. 49

A/ a = 28. 21 cm2 as well as 8. one particular cm2 sama dengan 3. forty-nine

4. A mechanic uses a hydraulic car jack to lift...
